Problem
A unit positive charge is moved successively between three points A, B and C.
• From A to B, an external agent does +3J of work.
• From B to C, the external agent does −2J of work.
(a) Arrange the points A, B and C in ascending order of electric potential.
(b) Calculate the potential difference VC−VA.
