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

`5muV`

B

`5mV`

C

`50muV`

D

`50mV`

Text Solution

Verified by Experts

The correct Answer is:
C
The emf developed between the ends of the conductor is `epsi=(1)/(2)Bl^(2) omega=(1)/(2)xx5xx0.2xx10^(-4)xx(1)^(2)`
`5xx10^(-5)V=50xx10^(-6)V=50muV`
