The dimensional formula for magnetic flu...

The dimensional formula for magnetic flux is :

A

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

B

`[ML^(0)T^(-2)A^(-2)]`

C

`[M^(0)L^(-2)T^(-2)A^(-2)]`

D

`[ML^(2)T^(-1)A^(3)]`

Text Solution

Verified by Experts

The correct Answer is:
A
`phi=ABcostheta` where `A`=area, `B`=magnetic induction
`:.phi=[L^(2)xxML^(0)T^(-2)A^(-1)]`
`=[ML^(2)T^(-2)A^(-1)]`
`:.(a)`is correct choice.
