Questions
A simple pendulum is attached to the roof of a lift. If time period of oscillation, when the lift is stationary is T. Then frequency of oscillation, when the lift falls freely, will be
detailed solution
Correct option is A
When lift falls freely effective acceleration and frequency of oscillations be zero geff=g-g=0 ⇒T'=2πlg-g=∞ , hence a frequency = 0.Talk to our academic expert!
