A simple pendulum of length 1m is attached to the ceiling of an elevator which is accelerating upward at the rate of `1m//s^(2)`. Its frequency is approximately :-

Passage X) A 2kg block hangs without vibrating at the bottom end of a spring with a force constant of 400 N/m. The top end of the spring is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of 5m/s^(2) when the acceleration suddenly ceases at t=0 and the car moves upward with constant speed. (g=10m/ s^(2) ) What is the angular frequency of oscillation of the block after the acceleration ceases?

A simple pendulum of length 1 m is freely suspended from the ceiling of an elevator. The time period of small oscillations as the elevator moves up with an acceleration of 2m//s^2 is (use g=10 m//s^2 )
