If E and B are respectively values of electric and magnetic fields, then which of following is dimensionless ?

A

`sqrt(mu_(0)in_(0))(E )/(B)`

B

`mu_(0)in_(0)(E )/(B)`

C

`mu_(0)in_(0)((B)/(E ))^(2)`

D

`(E )/(B).(mu_(0))/(in_(0))`

Text Solution

Verified by Experts

The correct Answer is:
A
`sqrt(mu_(0)in_(0))=(1)/(c )` and `(E )/(B)=c`
`therefore sqrt(mu_(0)in_(0)).(E )/(B)=(1)/(c )xx c =1`
`therefore` Dimensionless
