Two coils 'P' and 'Q' are separated by some distance. When a current of 3A flows through coil 'P' a magnetic flux of `10^(-3) Wb` passess through 'Q'. No current is passed through 'P' and a current of 2A passes through 'Q', the flux through of 'P' is :

A

`6.67xx10^(-3)` Wb

B

`3.67xx10^(-3)` Wb

C

`3.67xx10^(-4)` Wb

D

`6.67xx10^(-4)` Wb

Text Solution

Verified by Experts

The correct Answer is:
D
`phi_(OP)=10^(-3)=MI_P=Mxx3`
`phi_(PQ)=MI_Q=MxxI_Q = (10^(-3))/(3) xx 2 = 0.667 xx10^(-3) Wb`
`= 6.67 xx10^(-4) Wb`
