  1. Question 1

    Q1. A 500-kg car is moving at 20 m/s. What is the magnitude of the motional EMF induced in a 2-turn coil on its roof?

    • A) 5 × 10^-4 V
    • B) 2 × 10^-3 V
    • C) 3 × 10^-3 V
    • D) 1 × 10^-2 V

    Answer: 2 × 10^-3 V

    Explanation: Using Faraday's law of induction. Induced EMF is 2 * 500 * 20 * (1e-4) = 2e-3 V.
