A metal conductor of length 1m rotates vertically about one of its ends at angular velocity 5 radians per second. If the horizontal component of earth's magnetic field is `0.2xx10^(-4)T`, then the emf developed between the two ends of hte conductor is

A

`5 mu V`

B

`50 mu V`

C

5 mV

D

50 mV

Text Solution

Verified by Experts

The correct Answer is:
B
emf `=1/2Bl^2omega`
`=1/2xx.2xx10^-4xx1^2xx5`
= 50 mv
