The only force acting on the particle is the electric, Ask an Expert

Academics

A particle with a charge of -1.5 microcoulombs and a mass of 2.5x10^-6 kg is released from rest at point A and accelerates toward point B, arriving there weith a speed of 42 m/s. The only force acting on the particle is the electric force.

a.) what point is at the higher potential? give your reasoning.

b.) what is the potential difference VB-VA between A and B?
