Question

A The period of a simple pendulum does not depend on mass distribution within pendulum's shape but that of a physical pendulum does.

B The period of a physical pendulum does not depend on mass distribution within pendulum's shape but that of a simple pendulum does.

C The angular amplitude of a physical pendulum depends on length but that of a simple does not

D The angular amplitude of a simple pendulum depends on length but that of a physical pendulum does not

For Simple Pendulum , T =2pi sqrt(L/g)

For Phyiscal Pendulum , T = 2pi sqrt(I / mg *L_cm )

From these two equations we can see that Time period of physical pendulum depends on its mass distribution, shape etc.

(Because of I ( moment of inertia of physical pendulum about its centre of mass )

But Time period of simple pendulum dosen't depend upon mass deitribution.

so ,

A The period of a simple pendulum does not depend on mass distribution within pendulum's shape but that of a physical pendulum does.
