Question
A particle with a charge of -1.8 µC and a mass of 2.8 x 10-6 kg is released from rest at point A and accelerates toward point B, arriving
there with a speed of 45 m/s. The only force acting on the particle is the electric force. What is the potential difference VB-VA between
A and B? If VB is greater than VA, then give the answer as a positive number. If VB is less than VA, then give the answer as a negative
number.

During a particular thunderstorm, the electric potential between a cloud and the ground is Vcloud - Vground=2.5 x 108 V, with the cloud
being at the higher potential. What is the change in an electron's potential energy when the electron moves from the ground to the
cloud?
