A metallic conductor of 1m length is rotated verically its one end at an angular velocity of `5rad//sec`. If the horizontal component of earth's field is `0.2xx10^(-4)T`, the voltage generated at both ends of the conductor will be-

Options

A. 5 mV
B. `5 xx 10^(-4) V`
C. 50 mV
D. `50 mu V`

Answer

D

Explanation

`l = 1 m , B = 0.2 xx 10^(-4) T, W = 5 rad//s`
`V = 1/2 B omega I^2`
