The figure below shows a small, charged bead, with a charge of q = +37.0 nC, that moves a distance of d = 0.192 m from point A to point B in the presence of a uniform electric field E of magnitude 285 N/C, pointing right.
What is the magnitude (in N) and direction of the electric force on the bead?
What is the work (in J) done on the bead by the electric force as it moves from A to B?
What is the change of the electric potential energy (in J) as the bead moves from A to B? (The system consists of the bead and all its surroundings.)
What is the potential difference (in V) between A and B?
