Question

When one electron is taken towards the other electron, then the electric potential energy of the system ______

Options

• decreases.

• increases.

• remains unchanged.

• becomes zero.

Answer 1

When one electron is taken towards the other electron, then the electric potential energy of the system increases.

Explanation:

Potential energy of the system = `((-e)(-e))/(4piε_0r)`

= `(e^2)/(4piε_0r)`

Potential energy increases as r decreases.
