![]() What is the ratio of speeds of the two satellites?Īnswer: b 13. Two satellites of masses 50 kg and 100 kg revolve around the earth in circular orbits of radii 9R and 16R. Both move around the earth in the same orbit but the mass of B is twice that of the mass of A.ī) The orbital speed of A is twice that of BĬ) The orbital speed of B is twice that of Aĭ) The kinetic energy of both A and B are equalĪnswer: a 12. The time period of a satellite depends on _Ĭ) both mass of satellite and radius of the orbitĭ) neither mass of satellite nor radius of the orbitĪnswer: b 11. What is the ratio of the radius of their orbits?Īnswer: d 10. Consider 2 satellites A and B having time periods 16 hours and 1 hour, respectively. The time period of the moo n around the earth is 24 hours.Īnswer: b 9. The satellites orbiting the earth, eventually fall to the earth when they are left unsupervise d or unattended because _ī) of viscous forces causing the speed of the satellite and hence height to gradually decreaseĬ) the laws of gravitation predict such a trajectoryĪnswer: b 8. If the separation between the earth and the satellite is quadrupled, the new ti me period will be _Īnswer: d 7. The time period of a satellite of earth is 90 minutes. The time period of a satellite is independen t of the mass of the satellite.Īnswer: a 5. A satellite orbits the earth at a height of R/5. What is the time period of that satellite ?Īnswer: c 3. A satellite is revolving very close to a planet of density D. What is the percentage change in the time periods of the two sate llites?Īnswer: d 2. A satellite is launched into a circular orbit of radius R while a second satellite is launched into an orbit of radius 1.02R. We already published the most important Questions and Answers on the Chapter Gravitation. ![]() Here you will get all the details regarding Gravity MCQs and answers. Students don’t know how to tackle the exam questions on Gravitation. So students often stuck at that point while writing exams like JEE, NEET etc. While solving this topic it becomes more complicated due to lengthy theory. Gravitation is one of the most difficult chapter to master in Physics.
