A pendulum oscillates simple harmonically and only if
I. the sizer of the bob of pendulum is negligible in comparison with the length of the pendulum.
II. the angular amplitude is less than .
Choose the correct option.
Options
- ABoth I and II
- BOnly I
- COnly II
- DNone of these
Correct answer
A. Both I and II
Step-by-step solution
A simple pendulum in practice, consists of a heavy but small sized metallic bob suspended by a light, inextensible and flexible string.
It will oscillates simple harmonically, only if
(I) the size of the bob is negligible as compare to the length of the string of pendulum.
(II) the angle between the normal drawn at the mean position and string at extreme point or angular amplitude is less than .
Thus, both the statements are correct.
