Which of the following is the dimensional formula for capacitance `xx ("potential")^(2)`?

Options

A. `[ML^(2)T^(-1)]`
B. `[ML^(2)T^(-2)]`
C. `[ML^(-2)T^(-3)]`
D. `[ML^(-1)T^(-2)]`

Answer

a

Explanation

Energy stored in a capacitor is
`U=1/2 CV^(2)`
`:.` Dimensional formula for `CV^(2)=[ML^(2)T^(-2)]`
