1.	Consider a planet in some solar system which has a mass double the mass of the earth and density equal to the average density of the earth. An object weighing W on the earth will weighA. 2 wB. 3 wC. 3/wD. `2^(1//3)w`
Answer» Correct Answer - d `V_(P)=2V_(e)` `(4pi)/(3)xxR_(p)^(3)=2(4pi)/(3)xxR_(e)^(3)` `therefore" "R_(p)=root3(2)R_(e)` `F_(p)=(GM_(p)m)/(R_(p)^(2))`

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).
