In which case would electrical potential energy be built up and stored in the electric field? a) A positive charge is moved toward a negative charge. b) A positive charge is moved toward a positive charge. c) A negative charge is moved away from a negative charge. d) none of the above

The correct option is B

Explanation:

Although, it is common knowledge that in an electric field, unlike charges attract and like charges repel. However, to build up an electric potential, a positive charge is brought close to another positive charge - this causes work done to be changed to electric potential energy and stored in the electric field.

It should however be noted that when a negative charge is moved away from a positive charge, the negative charge gains electric potential energy.

it about 600 mph from what i calculated

gas and liquid
