The dimensional formula of electric flux is

Options

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

Answer

B

Explanation

Electric flux, `phi=intvecE*vecs`
The dimension of `phi` = Dimension of E `xx` dimension of s
`[phi]=[M^(1)L^(1)T^(-2)][AT]^(-1)[L^(2)]=[M^(1)L^(3)T^(-3)A^(-1)]`
