A boat is moving due east in a region where the earth's magnetic field is `5.0xx10^(-5) NA^(-1)m^(-1)` due north and horizontal. The boat carries a vertical aerial 2 m long. If the speed of the boat is `1.50 ms^(-1)`, the magnitude of the induced emf in the wire of aerial is

A

1 mV

B

0.75 mV

C

0.50 mV

D

0.15mv

Text Solution

Verified by Experts

The correct Answer is:
D
Induced emf `=Bxxvxxl`
`=5.0xx10^(-5)xx1.50xx2=10.0xx10^(-5)xx1.5`
`=1.5xx10^(-4)=0.15mV`
