A vertical metal rod of length 1 m moves at right angles to its length with a speed of 45 km/h in a direction making an angle of `60^(@)` with `B_(H)`. The emf induced in it is. `(B_(H)=3.6xx10^(-5)T)`

A

0.93 mV

B

0.74 mV

C

0.50 mV

D

0.39 mV

Text Solution

Verified by Experts

The correct Answer is:
D
`e=B_(H)lvsintheta`
`=(3.6xx10^(-5)xx1xx45xx10^(3)xxsin60)/(3600)`
`=0.39mV`
