Question

The dimensional formula of electric potential V is:

पर्याय

• \[[ML^2T^{-3}A^{-1}]\]

• \[[AT]\]

• \[[ML^2T^{-2}]\]

• \[[MLT^{-2}]\]

Answer 1

Electric potential has the SI unit Volt (V) and dimensional formula \[[ML^2T^{-3}A^{-1}]\]. It follows from \[V = U/q\], since U has dimensions \[[ML^2T^{-2}]\] and q has \[[AT]\].
