Question
STATEMENT-1: Time period of a simple pendulum remains unchanged if solid bob is replaced by a hollow bob of the same radius but lesser mass, because
STATEMENT-2: Time period of a simple pendulum depends on the mass but does not depend on the density.

Solution
The correct option is C Statement -1 is True, Statement-2 is False.
Time period of a simple pendulum only depends upon l and g,
Where, l is distance from the point of suspension to the centre of gravity of mass.
In the assertion neither the l alters nor the radius.Hence time period remains the same.
But the reason is false, as the time period doesn't depend upon mass.
Option C is the correct answer.
