- Q1.What is the gravitational potential energy of a body of mass m at a distance r from the center of the Earth of mass M?Easy
- Q2.A satellite is orbiting the Earth in a circular orbit of radius r. If the radius of the orbit is increased to 4r, what happens to the orbital speed of the satelEasy
- Q3.According to Kepler's third law of planetary motion, the square of the time period of a planet is proportional to which power of its semi-major axis?Easy
- Q4.If the mass of the Earth were doubled and its radius were halved, the acceleration due to gravity on its surface would become how many times its original value?Easy
- Q5.The escape velocity from the surface of the Earth is approximately 11.2 km/s. If a planet has twice the mass and twice the radius of the Earth, what is the escaEasy
