A vertical metal rod 1 m long performs linear SHM at right angles to `B_(H)` of `4xx10^(-5)Wb//m^(2)` with an amplitude of 5 cm and a period of `pis`. The values of maximum and minimum emfs induced in it are

A

`0muV,4V`

B

`4muV,0V`

C

`0muV,0V`

D

`4muV,4V`

Text Solution

Verified by Experts

The correct Answer is:
B
`e_(max)=B_(H)lv_(max)`
`=B_(H)laomega`
`=B_(H)la(2pi)/(T)`
`=(4xx10^(-5)xx1xx5xx10^(-5)xx2pi)/(pi)`
`=4xx10^(-6)V`
`=4muV`
`e_("min")=B_(H)lv_("min")=B_(H)lxx0=0V`
