A particle is fastened at the end of a string and is whirled in a vert

1.	A particle is fastened at the end of a string and is whirled in a vertical circle with the other end of the string being fixed. The motion of the particle is(a) periodic(b) oscillatory(c) simple harmonic(d) angular simple harmonic.
Answer» (a) periodic EXPLANATION: Since a uniform circular motion repeats itself at a regular time interval. (b) not true because it is not a to and fro motion. (c) not true because SHM is a special type of oscillation. (d) not true because the particle is not oscillating about a fixed axis.
