The wings of an aeroplane are I0m apart....

The wings of an aeroplane are `I0m` apart. The plane is moving horizontally towards the north with a velocity of `200m//sec` at a place where the vertical component of earth's magnetic field is `0.5xxI0^(-4)T` . The induced emf set up between the tips of the wings is

A

`0.1V`

B

`0.15V`

C

`1V`

D

`1.5V`

Text Solution

Verified by Experts

The correct Answer is:
A
`vec(v)=200hatjm//sec` , `vec(B)=-0.5xx10^(-4)hatkT` , `vec(l)=10hati`
`e=Bvl=0.5xx10^(-4)xx200xx10^(-4)xx200xx10=0.1V`
