The dimensional formula of `mu_(0) in_(0)` is ……..

Options

A. `M^(0)L^(-2)T^(2)`
B. `M^(0)L^(2)T^(-2)`
C. `M^(0)L^(1)T^(-1)`
D. `M^(0)L^(-1)T^(1)`

Answer

A

Explanation

`mu_(0)in_(0)=(1)/(C^(2))`, Where C = Speed of light
`therefore [mu_(0)in_(0)]=[C^(-2)]`
`= [M^(0)L^(1)T^(-1)]^(-2)=M^(0)L^(-2)T^(2)`
