The dimensional formula for electric field is

Options

A. `["ML"^(2)"T"^(-3)"A"^(-1)]`
B. `["ML"^(2)"T"^(-3)"A"^(-2)]`
C. `["MLT"^(-3)"A"^(-1)]`
D. `["M"^(0)"L"^(0)"T"^(0)"A"^(0)]`

Answer

C

Explanation

The unit of electric fields `E` is
`=("Newton")/("Coulomb")=("kg - metre sec"^(-2))/("ampere - sec") ="kg - metre sec"^(-3)"amp"^(-1)`
`therefore" "` Dimensions of electric field are `["MLT"^(-3)"A"^(-1)]`.
