The frequency of oscillation of a simple pendulum is f1. When the length of the pendulum l is increased to 2l, the frequency of oscillation of the simple pendulum is f2. The value of the ratio f1/f2 isSolutionShow solution >> The answer is D.The formula for the periodic time, T of a simple pendulum is given byand we know thatTherefore, the formula for f of a simple pendulum is given byNow we know
