Computer the work which must be performed to slowly pump the water out of a hemispherical reservoir of radius R=0.6m .

A small block of mass m os takes slowly up a fixed hemisphere from P to Q and then slowly down along its surface from Q to S by force F , which at each point of the surface, is tangential to the surface. If the coefficient of friction is mu , then the work performed by the force F in taking the block from P to S along the hemispherical surface of radius R is :

The maximum volume of a cone that can be carved out of a solid hemisphere of radius r is

The total amount of work that must be done on a body of mass m so that it escapes from the gravitational influence of a planet of radius R and mass M is given by

The amount of work done in pumping water out of a cubical vessel of height 1 m is nearly ( g = 10 ms^(-2))

Calculate the gravitational field intensity at the centre of the base of a hollow hemisphere of mass M and radius R . (Assume the base of hemisphere to be open)
