  • Q1 · Gravitation · MEDIUM

    At what height above the Earth's surface will the acceleration due to gravity be half its value on the surface? (R = radius of Earth)

  • Q2 · Gravitation · HARD

    Two satellites A and B are orbiting the Earth at heights R and 3R respectively, where R is the radius of Earth. The ratio of their time periods (TA/TB) is:
