If we hollow the ball of pendulum and fill it with sand, what would be the effect of change on the center of mass?

View answer and explanation

Correct option: D

Its value will first decrease and then increase

Option D is correct. Initially, the center of mass decreases as sand is added to the hollow ball. After it is completely filled, further addition of sand increases the center of mass.
