1.	An object of mass 2 kg is moved from infinity to a point P. Initially that object was at rest but on reaching P its speed is 2 m/s. The work done in moving that object is `-16J`. Then potential at P isA. 8 KJ/kgB. `-8J//kg`C. `4J//kg`D. `-4J//kg`
Answer» Correct Answer - b `"PE = work done"` `"E = -16J` `PE=G.P.xx"mass"` `16=G.P.xx2` `G.P.=(16)/(2)="8J/kg."`

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).
