A rod of mass `m` and length `l` is lying on a horizontal table. Work done in making it stand on one end will be

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 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 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?

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?

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. What is the speed of the chain, when it just loses contact with the table?

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. What is the speed of the chain, when it just loses contact with the table?

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 length 2m and mass 5kg is lying on a horizontal surface. The work done in raising one end of the rod with the other end in contact with the surface until the rod makes an angle 30^(@) with the horizontal is (g=10ms^(-2))
