The figure below shows a small, charged bead, with a charge of q = +44.0 nC, that moves a distance of d = 0.199 m from point A to point B in the presence of a uniform electric field
E
of magnitude 255 N/C, pointing right.

(a)
What is the magnitude (in N) and direction of the electric force on the bead?
magnitude Ndirection ---Select--- toward the right toward the left The magnitude is zero.

(b)
What is the work (in J) done on the bead by the electric force as it moves from A to B?

(c)
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.)
PEB − PEA =

(d)
What is the potential difference (in V) between A and B?
VB − VA =
