A. What is the potential a distance of 8.5 mm from a point charge of 7.6 uC?
B. How much would would it take to move a second charge of 4.9 uC from infinity to that a point that distance from the first charge? (this is the potential energy now stored in the system)
C. If you release the send charge, it will move away from the first. How much kinetic energy will it have once it is infinitely far away from the first charge?
D. How fast will it be moving, if it has a mass of 5.2x10^-9 kg and started from rest?

What is the distance between a -2.00 μC charge and a -3.00 μC charge if their potential energy is 0.491 J? To solve this question you want to think at where the charge q can be for example the -2.00 μC and the other charge -3.00 μC becomes the source of the voltage V. The initial distance is very far away, and the final distance is "r" that you want to find. ( Do not forget the voltage V for a point...

The Equation: is often used to calculate the electric potential from a point charge at an observation location. If we were to write this as a potential difference, we might write it as the potential difference from the observation to a point infinitely far away: The difference, Δν· is the quantity we can actually measure in the real world this is done by calibrating a voltage-measuring device to a location, and then moving elsewhere and reading off the difference in...
