Q. Identify correct statement among the following
A) The greater the mass of a pendulum bob, the shorter is its frequency of oscillation
B) A simple pendulum with a bob of mass $M$ swings with an angular amplitude of $40{^\circ}.$ When its angular amplitude is $20{^\circ},$ the tension in the string is less than $Mg\cos{20{^\circ}.}$
C) As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will decrease
D) The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum
Explanation
The correct answer is Option C: As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will decrease.
