Points A at (2, 3) m and B at (5, 7) m are in a region where the electric field is uniform and given by N/C. What is the potential difference VA - VB?
a. 33 V
b. 27 V
c. 30 V
d. 24 V
e. 11 V

Question 2

A particle (charge = 50 mC) 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
