A particle with a charge of -2.7 μC and a mass of 4.4 x 10-6 kg
is released from rest at point A and accelerates toward point B,
arriving there with a speed of 26 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.
