If C be the capacitance and V be the electric potential ,then the dimensional formula of `CV^(2)` is

Options

A. `M^(1)L^(2)T^(-2)A^(@)`
B. `M^(1)L^(1)T^(-2)A^(-1)`
C. `M^(0)L^(1)T^(-2)A^(@)`
D. `M^(1)L^(-3)T^(1)A^(-1)`

Answer

A

Explanation

Energy stored in a capacitor is
`u=(1)/(2)CV^(2)`
`therefore[CV^(2)]=[u]=[M^(1)L^(2)T^(-2)A^(@)]`
