Identify wrong statements among the following
The greater the mass of a pendulum bob, the shorter is its frequency of oscillation
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 Mgcos`20^(@)`. (3) The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum.
As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will also decreases.
