Question

A square loop of side 20 cm and resistance 1Ω is moved towards right with a constant speed v0. The right arm of the loop is in a uniform magnetic field of 5T. The field is perpendicular to the plane of the loop and is going into it. The loop is connected to a network of resistors each of value 4Ω. What should be the value of v0 so that a steady urrent of 2 mA flows in the loop ?

Select the correct option:

A

1 m/s

B

1 cm/s

C

$10^2 \mathrm{~m} / \mathrm{s}$

D

$10^{-2} \mathrm{~cm} / \mathrm{s}$
