If `C,` the velocity of light, `g` the acceleration due to gravity and `P` the atmospheric pressure in `M.K.S` units are the fundamental units then the dimension of length will be :

A

`C/g`

B

`(C )/(P)`

C

`P.C.g`

D

`(C^(2))/(g)`

Text Solution

Verified by Experts

The correct Answer is:
D
`(c^(2))/(g)=(L^(2)T^(-2))/(LT^(-2))=[L]`
`:.` Correct choice is `(d)`.
