e=Bvl= text0.1(2 × (10)- 2)× 6=12× (10)- 3=12mV

Q. A solid metal cube of edge length $2 c m$ is moving in the positive $y$ -direction at a constant speed of $6 m s^{- 1}$ . There is a uniform magnetic field of $0.1 T$ in the positive $z$ -direction. The potential difference between the two faces of the cube perpendicular to the $x$ -axis is

$12 mV$

$1 mV$

$2 mV$

$6 mV$

$e = B v l = 0.1 (2 \times (10)^{- 2}) \times 6 = 12 \times (10)^{- 3} = 12 mV$
