Question

a.In the drawing below, E = 4.0N/C and d = 1.5m. Calculate the work done by the electric field in moving a +5.0x10-9C charge from A to B. Be sure to include - sign if your answer is negative.

b.In the situation in diagram b above, calculate the potential energy difference between the +5.0x10-9C charge at B and at A. Be sure to include - sign if your answer is negative.

c.For the situation in diagram b above, calculate the potential difference between A and B. Be sure to include - sign if your answer is negative.

Explanation / Answer

W = potential * charge

V = E d = 4.0 * 1.5 = 6 V

W = 5 * 10-9 * 6

= 3 *10-8 J

---------------------------------------

enrgy due to pot difference = E d cos 90

= 0

distance d = d cos theta = 1.5 cos 30 = 1.299

V = Ed = 4 * 1.299

= 5.196 v
