(a) $A+5.00$ pC charge is located on a sheet of paper. (a) Draw to scale the curves where the equipotential surfaces due to these charges intersect the paper. Show only the surfaces that have a potential (relative to infinity) of $1.00 \mathrm{V}, 2.00 \mathrm{V}$ $3.00 \mathrm{V}, 4.00 \mathrm{V},$ and 5.00 $\mathrm{V} .$ (b) The surfaces are separated equally in potential. Are they also separated equally in distance? (c) In words, describe the shape and orientation of the surfaces you just found.

In physics, potential energy is the energy possessed by a body or a system due to its position relative to others, stresses within itself, electric charge, and other factors. The unit for energy in the International System of Units (SI) is the joule (J). One joule is the energy expended (or work done) in applying a force of one newton through a distance of one metre (1 newton metre). The term potential energy was introduced by the 19th century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concepts of potentiality. Potential energy is associated with forces that act on a body in a way that the work done by these forces on the body depends only on the initial and final positions of the body, and not on the specific path between them. These forces, that are called potential forces, can be represented at every point in space by vectors expressed as gradients of a scalar function called potential. Potential energy is the energy of an object. It is the energy by virtue of a position relative to other objects. Potential energy is associated with restoring forces such as a spring or the force of gravity. The action of stretching the spring or lifting the mass is performed by a force that works against the force field of the potential. This work is stored in the field, which is said to be stored as potential energy.

In physics, electric flux is a measure of the quantity of electric charge passing through a surface. It is used in the study of electromagnetic radiation. The SI unit of electric flux is the weber (symbol: Wb). The electric flux through a surface is calculated by dividing the electric charge passing through the surface by the area of the surface, and multiplying by the permittivity of free space (the permittivity of vacuum is used in the case of a vacuum). The electric flux through a closed surface is zero, by Gauss's law.

does this question? We have a charge that is five Picone Cummings tensions the next 12. And we want to find this distance. It has two different potentials. So we have some for potential Have b equals k too far. So in order to fight the distance from the charge to recruit potential surface, we have already close cake you over. Who so kay is night types tend to use in this, You turn your square columns square, and, um, courage is top five times tent. His elected focal and footage thiscause US 4.50 volts per centimeter over the witch and V is the footage officer could potential playing me. What? Okay, um so we can't plant in three equals. It asked us to find the planes. Went to sea for five balls so we could do that for me, E course. One foot to put scribbled for more than five foot, sir. Distance equals, um, we can just plug it in and calculated we get for five point of what five tube, either by one is for 25 centimetre. This is to put 25 says this 1.5 centimetre 1.125 sir. And zero point by centimeter. Okay, so if this is a positive charge, firstly, we do not. We know that's the potential plane. It will be a concentric spheres that is centered. It's this classic charge so on. So the question asked us to draw to scale off course. I am enjoying all the screens. This when I was happy, happy using a ruler because it it will ever different person which screened and a kid. But will you join a paper? You should use a drooling to joint so that the radius is exactly four, but five to Because because see Ozzy's distance and they're adorable. The paper Is it the question? Just ask. It has asked that you need to draw. Exactly. So do use your ruler and make sure Sezam five votes is gonna be a sphere. But are just draws a circle here because that's hung indicated sphere on the surface. Do make sure this is there a 0.5 centimeter as they're put on ice and we're using a ruler. So Okay, so this is five votes I would just try to roughly as a screen just from 3 to 5. Circosta skill Yeah, and for it, if we can see for it's not that much different. Actually, I might run out of space, so yeah, son of me makes this morning. So I have more space of its. This's for worlds three and three. Boat is 1.5, which has lived further from the forwards. People exist. So it is. The separation is living larger because we have roughly there put forward as a possible here. We only have a legal ones. This opportunity okay, two votes is even for Isa because I'll have servants. Seven send a bit of difference. So this might be, like toodles and finally went for my vote is over two centimeter larger. That U boat so well, vote is a huge circle. Um, ms, whether I have enough space. I mean, not when what might look kind of like this one vote. Okay, so I think the question the answer is obvious for part B apart, See, partly asks as the equally spaced off course or not, because you can see it's is is proportional to one over our. So it's not a linear relationship. It's the inverse relationship, and pretty much so for the further. You are from the charge so more slowly the potential were change. And Quincy asked others to describe surfaces while they're concentric spheres and the the common center is a point. Charge, yes, Internals a pointer and there a CZ three t sphere. But all the paper, we just draw this circles.
