A body of mass 2kg is thrown into space with escape velocity 11.2km/s, the escape velocity for another body of mass 5 kg will be .

A body of mass 5 kg is taken to the centre of the earth. What will be its mass there ?

A body of mass 4kg, is taken from a height of 5 m to a hegiht 10m. Find increase in potential energy.

A body of mass 4 kg is attached to another body of mass 2 kg with a massless rod. If the 4 kg mass is at (2i + 5j)m and 2 kg mass is at (4i + 2j)m, the centre of mass of the system is at (in m)
