Calculate the frequency if the number of revolutions is 300 per second and the paired poles are 50.
Correct answer: A. 15 kHz
- A. 15 kHz
- B. 150 kHz
- C. 1500 kHz
- D. 150 Hz
Explanation
Correct option is A.We know thatF = p × nF = 50 × 300F = 1500 Hz = 15 kHzAs this is a numerical thus only one option is correct.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
