Question

The dimensional formula of potential energy U is:

Options

• \[[MLT^{-3}]\]

• \[[ML^2T^{-3}A^{-1}]\]

• \[[ML^2T^{-2}]\]

• \[[AT]\]

Answer 1

Potential energy, measured in Joules, has the same dimensions as work: \[[ML^2T^{-2}]\]. It is the product of charge \[[AT]\] and potential \[[ML^2T^{-3}A^{-1}]\].
