A vertical metal rod of length 1.5 m is at rest in the earth's magnetic field of `B_(H)=4xx10^(-5)T`. If it starts moving at right angle to the magnetic meridian with a uniform acceleration of `5m//s^(2)`, then the instantaneous emf induced in it at the end of 2 s will be

A

0.6 mV

B

0.3 mV

C

0.5 mV

D

0.4 mV

Text Solution
