🤓 Based on our data, we think this question is relevant for Professor Lyuksyutov's class at TAMU.

Solution: A small object with negative charge q = -5.0 x 10 -4 C is released from rest at point a and moves in the electric field produced by other charges. At point b the object has kinetic energy 0.12 J. If the electric potential at point a due to the other charges is 600 V, what is the electric potential at point b? A) 360 V B) 840 V C) 120 V D) 240 V E) none of the above

Problem
