Unit and dimensional formula of volume charge density are.......

Options

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

Answer

A

Explanation

Volume charge density `rho =q/v, therefore` Unit `= C/m^(3)` and dimensional formula:
`|rho|= |q|/|V| =(A^(1)T^(1))/L^(3) = M^(0)L^(-3)T^(1)A^(1)`
