The dimensional formula of dielectric strength is…….

Options

A. `M^1L^1T^2Q^-1`
B. `M^1L^2T^-2Q^-1`
C. `M^-1L^-1T^2Q^1`
D. `M^-1L^-1T^2Q^2`

Answer

A

Explanation

Unit of dielectric strength= Unit of electric field
`=N/C`
`therefore` Dimensional formula of dielectric strength
`=([M^1L^1T^-2])/([Q^1])=[M^1L^1T^-2Q^-1]`
