Physical Pendulum Period – Rankers Physics

Angular SHM and Simple Pendulum: Practice Problem & Solution

Assertion (A): For a physical pendulum period of oscillation is maximum about an axis passes through centre of mass. Reason (R): A physical pendulum is in neutral equilibrium about centre of mass.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Angular SHM and Simple Pendulum. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A) is false. If a physical pendulum is pivoted at its center of mass, it will be in neutral equilibrium and will not oscillate, so there is no period. Reason (R) is true. A body pivoted at its center of mass is indeed in neutral equilibrium. Thus, (A) is false and (R) is true.
