A Particle (Charge = 50 μC) Moves in a Region

A particle (charge = 50 μC) moves in a region where the only force on it is an electric force. As the particle moves 25 cm from point A to point B, its kinetic energy increases by 1.5 mJ. Determine the electric potential difference, VB − VA.

A) −50 V
B) −40 V
C) −30 V
D) −60 V
E) +15 V
