What are the sign and magnitude of a point charge that produces a potential of –2.00 V at a distance of 1.00 mm?

The magnitude of the point charge is: $2.22 \times 10^{-13} \mathrm{C}$ and it is a negative charge.

supposed to find magnitude and the sign of the charge, given the potential at some distance so so forced information we were given the potential is negative to wound. Sensitized negative sign here implies that charge has to be negative. You can also verify that he was in equation with V equals K times Q. Divided by distance from the charge. Now we are supposed to find the charge here. Six charge was negative. Potential will be negative. Says they have the same same sign not charge from this equation is given by are times we'd buy the bike, eh? Let's substitute all the numerical values Our is one millimeter. So there's 10 power *** to three meters. Potential is negative, too divided by the cave value of case nine times 10 per night. So let's solve this. This gives you the value Q. Equal to 0.22 two Williams so you can see that it is a 10 pounder. The 23 here in power has a 29 here that will give us 10 power Negative 12. Cool. So that's the net charge. Also, there is negative sign so you can write this as zero point 222 Pico Kalume. So I guess that negative sign will give us negative charge Was true. Was right charge is negative.
