A helicopter rises vertically upwards with a speed of 100 `m//s`. If the helicopter has a length of 10m and horizontal component of earth's magnetic field is `5 xx 10^(-3)Wb//m^(2)`, then the induced emf between the tip of the nose and the tail of the helicopter is

A

5V

B

25V

C

50V

D

0.5V

Text Solution

Verified by Experts

The correct Answer is:
A
The induced emf between the tip of the nose and the tail of the helicopter is given by
`e=B_(H)vl = 5 xx 10^(-3) xx 100 xx 10 = 5V`.
