1.	If the radius of the earth was half of its present value and its mass `(1//8)^("th")` of the present mass, the g value would have been reduced toA. `(1)/(8)g`B. `(1)/(2)g`C. `(1)/(3)g`D. g
Answer» Correct Answer - b `(g_(2))/(g_(1))=(m_(2))/(m_(1))xx((R_(1))/(R_(2)))^(2)=(1)/(8)xx4=(1)/(2)` `g_(2)=(1)/(2)g_(1).`

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).
