Question

The symbol, SI unit, and nature of electrostatic potential energy are respectively:

Options

• V, Volt (V), vector quantity

• W, Joule (J), vector quantity

• U, Joule (J), scalar quantity

• U, Newton (N), vector quantity

Answer 1

The electrostatic potential energy is denoted by the symbol U, is measured in Joule (J) in SI units, and is a scalar quantity because it represents total work done, which adds algebraically without any direction.
