1.	A satellite which is geostationary in a particular orbit is taken to another orbit. Its distance from the center of earth in new orbit is two times of the earlier orbit. The time period in second orbit is …… hours.(a) 4.8(b) 48√2(c) 24(d) 24√2
Answer» Correct answer is (b) 48 √2 Hint : T∝ \(r^\frac{3}{2}\) if r becomes double then time period will become (2)^{\(\frac{3}{2}\)}so the new time period will be 24 x 2√2 hours. i.e., 48√2 hours.

Answer»

Correct answer is (b) 48 √2

Hint : T∝ \(r^\frac{3}{2}\) if r becomes double then time period will become (2)^{\(\frac{3}{2}\)}so the new time period will be 24 x 2√2 hours. i.e., 48√2 hours.

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).
