Question number: 1760
Identify wrong statements among the following,
(1) The greater the mass of a pendulum bob, the shorter is its frequency of oscillation
(2) A simple pendulum with a bob of mass m swings with an angular amplitude of 40°. When its angular amplitude is 20°, the tension in the string is less than mg cos 20 0.
(3) As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will also increase.
(4) The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum.
