CUET · PHYSICS · PYQ PAPER 2025

A girl peddles a stationary bicycle. The pedals of the bicycle are attached to a N = 100 turn coil of area \( A = 0.10 \text{ m}^2 \). The coil completes one revolution in T = 2 seconds, and it is placed in a uniform magnetic field of B = 0.02 T perpendicular to the axis of rotation of the coil. The maximum voltage generated in the coil will be

  1. A 0.314 V
  2. B 3.14 V
  3. C 6.28 V
  4. D 0.628 V
Verified Solution

Answer & Solution

Correct Answer

(D) 0.628 V

Step-by-step Solution

Detailed explanation

\( \varepsilon_{max} = NBA\left(\frac{2\pi}{T}\right) = (100)(0.02)(0.10)\left(\frac{2\pi}{2}\right) = 0.628 \text{ V} \)
