1.	Two satellite of same mass are launched in the same orbit of radius `r` around the earth so as to rotate opposite to each other. If they collide inelastically and stick together as wreckage, the total energy of the system just after collision isA. `-(2GMm)/(r)`B. `-(GMm)/(r)`C. `(GMm)/(2r)`D. zero
Answer» Correct Answer - A If they collide inelastically and stick together as wrekage, then KE = 0, only PE is present `:. E=U=2(-(GMm)/(r))=-(2GMm)/(r)` .

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
