A spherical shell filled with water is hung from a string to form a simple pendulum. What happens to the time period if the water freezes? Does shell size matter? For a shell small compared with the string length, freezing the water makes the time period:
Options:
Answer:
C
Solution:
The period depends on the length from the support to the centre of mass, not on the mass. Freezing changes neither. For a large shell the radius adds to the effective length and the rotational inertia adds a small correction, but the effect of freezing alone stays negligible.
