Question

calculate the energy possessed by 10^10 electrons after moving in vacuum through a potential difference of 2000 volt​

Answer 1

Answer:

Energy is required to cause a positive test charge to move against the electric field between the negative and the positive terminal. ... The ratio of the change in potential energy to charge is 12:1. Thus, 24 Joules would be the difference in potential energy for 2 Coulombs of charge.
