A metre scale of mass 200 g, is lying on a horizontal table. What is the work done by student in making it stand vertically on one of its ends?

A uniform rod of mass 2kg and length l is lying on a horizontal surface. If the work done in raising one end of the rod through an angle 45^(@) is 'W' , then the work done in raising it further 45^(@) is

A rod AB of mass M and length L lies on smooth horizontal table impulse J is applied to end A as shown in the figure immediately after imparting the impulse :

A uniform rod of mass 2kg. And length 1m is lying on a horizontal surface. If the work done in raising one end of the rod through an angle 45^(@) is .W., the work done in raising it further through 45^(@) is,

A uniform rod of mass m and length l is lying on a smooth table. An impulse J acts on the rod momentarily as shown in figure at point R. Just after that:

A uniform rod of length 4 m and mass 20 kg is lying horizontal on the ground. The work done in keeping it vertical with one of its ends touching the ground, will be -

A uniform chain of mass m and length l is lying on a horizontal table with one-third of its length hanging over the edge of the table. If the chain is limiting equlibrium, what is the coefficient of friction for the contact between table and chain?
