PLEASE HELP VERY IMPORTANT!!!
A charge q of 7.3 × 10^15 coulomb moves from point A to point B in an electric field. If the potential energy of the charge at point A is 3.5 × 10^-12 joules and that at point B is 1.3 × 10^-12 joules, what is the potential difference between point A and B?

anonymous · Answer

Divide potential energy by charge to get potential.

anonymous · Answer

Remember 1 volt = 1 joule per coulomb

anonymous · Answer

Use the formula for PD, which is joules per Coulomb in simplest terms. 
This you can also write it as ((3.5-1.3)*10^-12)/7.3*10^15
