Question

How much work must we do on a proton to move it from point A, which is at a potential of +50V, to point B, which is at a potential of -50 V, along the semicircular path shown in the figure? Assume the system is isolated from outside forces.

(e = 1.60 × 10^-19 C)

A.) 1.6 J

B.) 1.60 × 10^-17 J

c.) -1.60 × 10^-17 J

D.) -1.6 J

E.) This cannot be determined because we do not know the distance traveled.

Answer 1

Comment the work done was found to be -1.6*10^-17 J
