Q2 · Gravitation · HARD
Two satellites of masses m and 2m are revolving around Earth in orbits of radii r and 2r respectively. What is the ratio of their time periods?
Q3 · Gravitation · MEDIUM
At what height above Earth's surface will the acceleration due to gravity be half its value on the surface? (Take radius of Earth = R)
Q4 · Gravitation · HARD
A satellite orbits Earth at a height equal to Earth's radius R above the surface. If the acceleration due to gravity at Earth's surface is g, what is the orbital speed of the satellite?
Q5 · Gravitation · EASY
The weight of an object on the Moon is one-sixth of its weight on Earth. If an object weighs 60 N on Earth, what is its mass?
