Answer the following questions:
(a) Time period of a particle in SHM depends on the force constant k and mass m of the particle: \mathbf{T}==2 \pi(\sqrt{m} / \sqrt{k}). A simple pendulum executes SHM approximately. Why then is the time period of a pendulum independent of the mass of the pendulum?
(b) The motion of a simple pendulum is approximately simple harmonic for small-angle oscillations. For larger angles of oscillation, a more involved analysis shows that \mathbf{T} is greater than 2 \pi(\sqrt{I} / \sqrt{g}) . Think of a qualitative argument to appreciate this result.

(a) The spring constant k is proportional to the mass in the case of a simple pendulum. The numerator (m) and denominator (d) will cancel each other out. As a result, the simple pendulum’s time period is independent of the bob’s mass.

(b) The expression for the restoring force acting on the bob of a basic pendulum is

F=-m g \sin \theta

F= restoring force

\mathrm{m}= mass of the bob

\mathrm{g}= acceleration due to gravity

\theta= angle of displacement

When \theta is small, \sin \theta \approx \theta.

Then the expression for the time period of a simple pendulum is given by \mathrm{T}=2 \pi(\sqrt{I} / \sqrt{g})

sin \theta < \theta when \theta is huge. As a result, the equation above is invalid. In the time period T, there will be an increase.
