Question
Select the incorrect statement(s) from the following.
I. A simple harmonic motion is necessarily periodic.
II. A simple harmonic motion may be oscillatory
III. An oscillatory motion is necessarily periodic
- I only
- I and II
- II and III
- I and III
Hint:
An SHM is a to and fro motion
The correct answer is: II and III
An SHM is a to and fro motion and hence it is necessarily oscillatory and hence this statement is incorrect.
