A heavy uniform rod is hanging vertically from a fixed support. It is stretched by its own weight. The diameter of the rod is
1 smallest at the top and gradually increases down the rod
2 largest at the top and gradually decreases down the rod
3 uniform everywhere
4 maximum in the middle
Explanation:
A Force or tension at the top is due to the largest portions of weight. At the bottom, it is very small. Therefore, the diameter of the rod is minimum at the top and gradually increases down the rod.

A solid sphere is rotating in free space. If the radius of sphere is increased keeping mass same which one of the following will not be affected?
1 Angular velocity
2 Angular momentum
3 Moment of inertia
4 Rotational kinetic energy
Explanation:
B In free space, neither acceleration due to gravity nor external torque act on the rotating solid sphere. Therefore, taking the same man of sphere, if radius is increased, then moment of inertia, rotational kinetic energy and angular velocity will change but according to law of conservation of momentum angular momentum will not change.

A wire is stretched under a force. If the wire suddenly snaps the temperature of the wire
1 remains the same
2 decreases
3 increases
4 first decreases then increases
Explanation:
C Work done by stretched wire to strain. It will stored as energy which is converted into. So, the temperature of the wire will increase.
