The dimension of `((1)/(2))epsilon_(0)E^(2)` (`epsilon_(0)` : permittivity of free space, E electric field

Options

A. `[MLT^(1)]`
B. `[ML^(2) T^(2)]`
C. `[ML^(-1) T^(-2)]`
D. `[ML^(2) T^(-1)]`

Answer

C

Explanation

(3) `(1)/(2) epsilon_(0) E^(2)` is `en ergy//volume`
`(ML^(2) T^(-2))/(L^(3)) = [ML^(-1) T^(-2)]`
