Two particles P and Q are moving as shown in the figure. At this moment of time the angular speed of P w.r.t. Q is

`5" rads"^(-1)`

`4" rads"^(-1)`

`2" rads"^(-1)`

`1" rads"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:

EMF induced across the ends of each spoke `=(Br^(2)omega)/(2)`
`therefore` EMF across 8 spokes are in parallel.
`therefore` Effective emf `=(1)/(2)r^(2)omegaB`
