At a certain point in space there is a potential of 400 V. What is the potential energy of a +2-μC charge at that point in space?

Question

Quizplus · Accepted Answer

The potential energy of a charge is given by the formula U = qV, where q is the charge and V is the potential. Plugging in the given values, we get:
U = (2 μC)(400 V)
U = 800 μJ = 8 × 10^-4 J = 8 × 10^-14 J (in scientific notation with proper units)
Therefore, the answer is (E).
