A particle is secured to the end of a string and whirled in a vertical circle while the opposite end of the string remains fixed. The motion of the particle is

Step-by-step solution

When a particle is whirled in a vertical circle, it continuously moves along the circular path, completing revolutions in a single direction. Since the particle repeats its entire trajectory after a definite interval of time, its motion is periodic. Because the particle does not move to and fro about a mean equilibrium position, the motion is neither oscillatory nor simple harmonic.
