A conducting rod of length l is hinged at point O. It is free to rotate in a vertical plane. There exists a uniform magnetic field \(\overrightarrow{\mathrm{B}}\) in horizontal direction. The rod is released from the position shown in the figure. The potential difference between the two ends of the rod is proportional to:
- l 3/2
- l 2
- sin θ
- (sin θ)1/2
Answer
(A) l 3 /2, (D) (sin θ ) 1/2
