Question

A charge q moves from point A to point B in an electric field. The potential energy of the charge at point A is 5.6 × 10-10 joules and that at point B is 2.3 × 10-10 joules. If the kinetic energy at point A is zero, what is the kinetic energy at point B?
A. 5.6 × 10-12 joules
B. 1.3 × 10-12 joules
C. 2.3 × 10-12 joules
D. 3.3 × 10-10 joules
E. 5.6 × 10-10 joules
