Solution

Q.
A metallic cube of side 15 cm moving along y-axis at a uniform velocity of $2 {ms}^{- 1}$ . In a region of uniform magnetic field of magnitude 0.5 T directed along z-axis. In equilibrium the potential difference between the faces of higher and lower potential developed because of the motion through the field will be _________ mV. [2023]

Ans.
(150)

$Δ V = (v \times B) d$

$Δ V = (2 \times \frac{1}{2}) \times 0.15$

$Δ V = 150 mV$
