The time period of a simple pendulum is given by the formula, T = 2pi sqrt(l//g), where T = time period, l = length of pendulum and g = acceleration due to gravity.
If the length of the pendulum is decreased to 1/4 of its initial value, then what happens to its frequency of oscillations ?

Answer:
T=2π√l/g.... initially.
now T=2π√l/4g
now... after solving T=√l
so,, frequency,f= 1/√l.
thank you
