Question

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. your answer needs to be in j but you don't need to enter the unit in your answer for this question.

Answer 1

F=q*e

=5*10^-9*4

=2*10^-8

therefore work done=F*d

=2*10^-8*1.5

=3*10^-8J
