Answer to Question #303913 in Physics for Ashley

Question

A 4.5 C charge requires an 8.0 J to move it from point X to Y, where the potential

difference is 1.5 V. Calculate (a) the potential difference between points X and Y. (b) the

potential at point Y.

Answer 1

a) By definition, the potential difference is the work per unit charge:

$$V_{XY} = \dfrac{8.0J}{4.5C} \approx 1.8V$$

b) There is no enough information to answer on this question. In order to find the

potential at point Y, the potential at point X should be given.
