A metre gauge train is running towards north with a speed of `20 m//s`. If the vertical component of earth's magnetic induction is `3 xx 10^(-4) Wb//m^(2)` , then the e.m.f. induced at the end of the axle is

A

3 mV

B

6 mV

C

12 mV

D

18 mV

Text Solution

Verified by Experts

The correct Answer is:
