Question

Electric Potential V at a point in an electrical field is ______.

Options

• potential energy of a unit charge placed at that point.

• potential energy of a proton placed at that point.

• potential energy of an electron placed at that point.

• potential energy of all charges in the field. 

Answer 1

Electric Potential V at a point in an electrical field is potential energy of a unit charge placed at that point.

Explanation:

The work done in bringing a unit positive charge from infinity to a point in an electric field is called electric potential V, and the work done in bringing any finite charge from infinity to a point in an electric field is called potential energy U.

They are related as, U = qV

If q = 1C, U = V
