The electric potential at the origin of an xy-coordinate system is 40 V. A -8.0-μC charge is brought from x = +∞ to that point. What is the electric potential energy of this charge at the origin?

Question

Quizplus · Accepted Answer

The electric potential energy (U) is given by U = qV, where q is the charge and V is the potential. Here, U = (-8.0 × 10^-6 C)(40 V) = -3.2 × 10^-4 J.
