# Electrical potential energy question.Watch

#1
Calculate the amount of electrical potential energy gained by an electron when it is moved from infinity to a point 0.5cm from another electron.

1. I have used V = 1/(4"π" ε0" " )xQ/r
2. Then I used W=QV to get the energy
3. The answer I got is : 4.6x10^-26
