Two Point Charges Are Separated by 1

question 13

Multiple Choice

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