In physics, a charge is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge is a characteristic property of many subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields. The interaction between a moving charge and the electromagnetic field is the source of the electromagnetic force, which is one of the four fundamental forces.

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.

over here we have to be subject to a distance of weapon time. And now there are no. So if the process between them are become triple then what is the new new distance between the rights? A very simple question. We know that it is you know that the course will be ready to charge particle over here. The fourth we need to part particularly given the X equals two. Take you you want to upon our square right? So are a distance between them to a strategy in its only place at the distance of our Then 8.5, then it has four. Right? And when some distance we already know that force will agree. Only if only if distance will agree because this and these three are constant. So it forces including the distance integrating. So it will continue. So now after X equals to keep you want you to upon our one squad. Right? And this F one is uh This F one overhead. Use it. Uh Force Okay I have guys equals 2 3 times of that. Right? So you can say you want to upon our squad equal to kick you want you to upon our one spot? Right? So this one is one And three times of read one. So our one squad that will be three times of our squad. Right? So I want it was too those three times of What is the initial distance? 38.5. And in the 145 minute centimeter. Okay, so we need to find the root Squire of this one. First of all, we need to multiply with 8.45 into three. It will come up to 25 135 routes on the right. So we need to find another route of 25 35 Right? So it will consult to be new restaurants that will consult B. R. One. That is five point of 034 and in the center. Okay thank you.
