Which one of the following is not correct ?

Options

A. Dimension formula of thermal conductivity `(K)` is `["M"^(1)"L"^(1)"T"^(-3)"K"^(-1)]`
B. Dimension formula of potential `(V)` is `["M"^(1)"L"^(2)"T"^(3)"A"^(-1)]`
C. Dimension formula of permeability of free space `(mu_(0))` is `["M"^(1)"L"^(1)"T"^(-2)"A"^(-2)]`
D. Dimensional formula of `RC` is `["M"^(0)"L"^(0)"T"^(-1)]`

Answer

B

Explanation

Dimensional formula of potential `[V]=["M"" L"^(2)"T"^(-3)"A"^(-1)]`
Dimensional formula of `[RC]=["M"^(0)"L"^(0)"T"]`
