Two point charges are separated by 1.00 x 10-2 m. One charge is -2.8 x 10-8 C; and the other is +2.8 x 10-8 C. The points A and B are located 2.5 x 10-3 m from the lower and upper point charges as shown
If an electron, which has a charge of 1.60 x 10-19 C, is moved from rest at A to rest at B, what is the change in electric potential energy of the electron?
