A conducting wheel in which there are four rods of length $25 cm$ as shown in the figure is rotating with constant angular velocity $20 rad / s$ in a uniform magnetic field $8 T .$ The induced potential difference between its centre and rim will be

Options:

Answer:

Solution:

$V (induced) = \frac{1}{2} B ω ℓ^{2}$

$= \frac{1}{2} \times 8 \times 20 \times {(\frac{25}{100})}^{2} = 5 V$
