Assertion (A) : Time period of a hollow ...

Assertion (A) : Time period of a hollow ball will be more than that of a solid ball of same radius.
Reason (R ) : Time period is independence of mass or distribuiton but on `sqrt(l)`, where `l` is the distance between the point of suspension and the centre of the bob.

A

Assertion is True, Reason is True, Reason is correct explanation for Assertion.

B

Assertion is True, Reason is True, Reason is not correct explanation for Assertion.

C

Assertion is True, Reason is False.

D

Assertion is False, Reason is True.

Text Solution

Verified by Experts

The correct Answer is:
D
Assertion is false, since effective length is not altered.
Reason is true since `T=2pisqrt((l)/(g))`
So, choice (`d`) is correct.

Assertion : time period of a simple pendulum does not depend on the mass of the bob Reason : the restoring force is independent of the mass of the bob

A ball of radius r is made to oscillate in a bowl of radius R, find its time period of oscillation.

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

A rigid body is to be suspended like a physical pendulum so as to have a time period of T = 0.2pi second for small amplitude oscillations. The minimum distance of the point of suspension from the centre of mass of the body is l_(1) = 0.4 m to get this time period. Find the maximum distance (l_(2)) of a point of suspension from the centre of mass of the body so as to get the same time period. [g = 10 m//s^(2)]

Assertion : The bob of a simple pendulum is a ball full of water, if a fine hole is made in the bottom of the ball, the time period first increases and then decreases. Reason : As water flows out of the bob the weight of bob decreases.

A pendulum of length L carries a negative charge -q on the bob. A positive charge +q is held at the point of support. Then, the time period of the bob is
