What happens, when we multiply a vector by (-5) ?

A

`[L^(-1)T]`

B

`[L^(2)T^(2)]`

C

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

D

`[LT^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
C
As we know that formula of velocity is
`v=(1)/sqrt(mu_(0)epsilon_(0))rArr v^(2)=1/(mu_(0)epsilon_(0))=[LT^(-1)]^(2)`
`:. (1)/(mu_(0)epsilon_(0))=[L^(2)T^(-2)]`
