The dimensions of `(1)/(2) in_(0) E^(2)`, where `in_0` is permittivity of free space and E is electric field, is :-

A

`[MLT^(-1)]`

B

`[ML^(2)T^(-2)]`

C

`[ML^(-1)T^(-2)] `

D

`[ML^(2)T^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
C
`(1)/(2) in_0 E^(2)` = Energy density = `("Energy")/("Volume")= [M^(1)L^(-1)T^(-2)]`
