A straight rod of length `l` si rotating about axis passing through `O` is shown. A uniform magnetic field `B` exists parallel to the axis of rotation. `E.m.f` induced between `P` and `Q` is:

`8/(25) Bomegal^2`

`3/(10)B omegal^2`

`7/(25)B omegal^2`

zero

Text Solution

Verified by Experts

The correct Answer is:

`e=Bomegaint(-l//5)^(4l//5)x dx =(3B omegal^2)/(10)`
