Problem

A unit positive charge is moved successively between three points A, B and C. • From A to B, an external agent does

+3\,\text{J}

of work. • From B to C, the external agent does

-2\,\text{J}

of work. a. Arrange the points A, B and C in ascending order of electric potential. b. Calculate the potential difference

V_C - V_A
