A particle moves uniformly around a circle of radius 5.0 cm at 2.0 revolutions per second. What are the amplitude and frequency of the SHM performed by its projection on a diameter?
Correct answer B. 5.0 cm and 2.0 Hz
Explanation
The projection of uniform circular motion onto a diameter is SHM whose amplitude equals the radius, 5.0 cm, and whose frequency equals the revolutions per second, 2.0 Hz. The angular frequency would be 4π rad/s.
