A point charge q = +38.0 uC moves from A to B separated by a distance of d = .17

Question

A point charge q = +38.0 uC moves from A to B separated by a distance of d = .175 m in the presence of an external electric field E  of magnitude 279 N/C directed toward the right as in the following figure.

A) find the electric force exerted on the charge.

                    Magnitude = _______N

                    Direction = ________

B) Find the work done by the electric field. ________J

C) Find the change in the electric potential energy of the charge _________J

D) Find the potential difference between A and B. VB - VA = _________V

Find the work done by the electric field. ________J Find the change in the electric potential energy of the charge _________J Find the potential difference between A and B. VB - VA = _________V

Explanation / Answer

A) force= 279*38*10^-6 = 0.010602 N

direction = towards right

B) work done = F*d = 0.010602*0.175 = 0.00185535 J

C) change in potential energy = -0.00185535 J

D) Vb
