Question

The figure below shows a small, charged sphere, with a charge of q = +45.0 nC, that moves a distance of d = 0.182 m from point A to point B in the presence of a uniform electric field

of magnitude 255 N/C, pointing right.

(a)

What is the magnitude (in N) and direction of the electric force on the sphere?

magnitude Ndirection ---Select--- toward the right toward the left The magnitude is zero.

(b)

What is the work (in J) done on the sphere 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 sphere moves from A to B? (The system consists of the sphere and all its surroundings.)

PE_B − PE_A = J

(d)

What is the potential difference (in V) between A and B?

V_B − V_A = V
