🤓 Based on our data, we think this question is relevant for Professor Kara's class at UCF.
A uniform electric field, with a magnitude of 15 x10 2 N/C, is directed parallel to the positive x-axis. The work done by the electron as it moves from A (x = 2 m) to B (x = 7 m) is -3.2 x 10-16 J. If potential at A is +5000 V, what is the potential at B? (For an electron q = -1.6 x 10 -19 C)
(a) -2800 V
(b) +3000 V
(c) +7000 V
(d) -2000 V
