a)

A particle (charge = 70 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 4.2 mJ. Determine the electric potential difference, VB - VA. (in Volts)

b)

Points A [at (3, 1) m] and B [at (8, 8) m] are in a region where the electric field is uniform and given by E→=(4iˆ+3jˆ)E→=4i^+3j^A- VB? (in Volts)
