Question 9 1 pts How much work must we do on an electron 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) +50V -50V O 1.6 1.60x 10-17 -1.60x 10-17 O-1.6J This cannot be determined because we do not know the distance traveled
