Question

Which one of the following is a simple harmonic motion? (A) wave moving through a string fixed at both ends (B) earth spinning about its own axis (C) ball bouncing between two rigid vertical walls (D) particle moving in a circle with uniform speed

Simple harmonic waves are set up in the string fixed at both two ends.
Earth spinning about its own axis, ball bouncing between two rigid vertical walls and particle moving in a circle with uniform speed, all these are periodic but not simple harmonic.
