Solution

Q.
A rod of length 60 cm rotates with a uniform angular velocity 20 rad $s^{- 1}$ about its perpendicular bisector, in a uniform magnetic field 0.5 T. The direction of magnetic field is parallel to the axis of rotation. The potential difference between the two ends of the rod is ______ V. [2024]

Ans.
(0)

$V_{B} - V_{C} = \frac{B_{0} ω l^{2}}{8}$

$V_{A} - V_{C} = \frac{B_{0} ω l^{2}}{8}$

$V_{B} - V_{A} = 0$
