What is the frequency of the simple pendulum if its in the lift which is accelerating upwards at 2.00 m/s^2 . Given that the length of pendulum is 0.248 m .
I am not sure what 's the acceleration of gravity ..
The more intuitive (and simpler) answer is to ask yourself: do you feel heavier or lighter when a lift is accelerating upwards? The answer, of course, is heavier. So the acceleration of the lift is added to the acceleration due to gravity.
