Homework Statement



I need help with the problems stated below, I know i could figure them out if somebody would show me the proper formulas, and maybe a quick explanation of the variables used in the formula ?

Homework Equations



A particle moves through a distance of 10 m along an electric field of strength 75 N/C. Its electrical potential energy decreases by 4.8 x 10-16 J. What is the charge of the particle?

A particle moves through a distance of 10 m along an electric field of strength 75 N/C. Its electrical potential energy decreases by 4.8 x 10-16 J. What is the potential difference between the initial and final locations of the particle?

An electron moves 4.5 m in the direction of an electric field of strength 325 N/C. The change in electrical potential energy is:

Which one of the following relations is correct?

The Attempt at a Solution
