Question

Determine the time period of a simple pendulum of length = l when mass of bob = m Kg?​

Answer 1

Answer:

M = Mass of B ob x = Displacement = OB l = length of simple pendulum Let the bob is displaced through a small angle θ the forces acting on it:- 1) weight = Mg acting vertically downwards. 2) Tension = T acting upwards. Divide Mg into its components → Mg Cos θ & Mg Sin θ T = Mg Cos θ F = Mg Sin θ - ve sign shows force is divested towards the ocean positions. If θ = Small,

1.) Time period depends on length of pendulum and ‘g’ of place where experiment is done.

2) T is independent of amplitude of vibration provided and it is small and also of the mass of bob.
