A 6.0 μC negative charge is attracted to a large,well-anchored,positive charge.How much kinetic energy does the negatively charged object gain if the potential difference through which it moves is 3 mV?

Question

Quizplus · Accepted Answer

The kinetic energy gained by the charge is equal to the work done on it, which is the product of the charge and the potential difference. KE = qV = (6.0 x 10^-6 C)(3 x 10^-3 V) = 18 x 10^-9 J = 18 nJ.
