MCQ
A simple pendulum is vibrating in an evacuated chamber, it will oscillate with
- AIncreasing amplitude
- ✓Constant amplitude
- CDecreasing amplitude
- DFirst (C) then (a)
✓
Answer
Correct option: B.
Constant amplitude
b
(b)As it is clear that in vacuum, the bob will not experience any frictional force. Hence, there shall be no dissipation therefore, it will oscillate with constant amplitude.
