Physics Question on Oscillations
A pendulum is suspended from the ceiling of the compartment of train. When the train is stationary, the time period of the pendulum is T. If the train accelerates, the time period of the pendulum will
A
increase
B
decrease
C
remain unchanged
D
be infinity
Answer
decrease
Explanation
Solution
The pendulum comes under two accelerations (g and a) in mutually perpendicular directions. Hence resultant accelerations increases, because of which T decreases
