Question 1

A particle (charge = 5.0 μC) is released from rest at a point x = 10 cm. If a 5.0-μC charge is held fixed at the origin, what is the kinetic energy of the particle after it has moved 90 cm?

◦
1.6 J

◦
2.0 J

◦
2.4 J

◦
1.2 J

◦
1.8 J


Question 2

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.

◦
−50 V

◦
−40 V

◦
−30 V

◦
−60 V
