Physics Question on Oscillations
A simple pendulum is vibrating in an evacuated chamber, it will oscillate with:
A
increasing amplitude
B
constant amplitude
C
decreasing amplitude
D
first (c) then (a)
Answer
constant amplitude
Explanation
Solution
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.
