A 360-kg satellite is in orbit around the Earth 10000 km above the Earth's surface.

(a) What is the weight of the satellite when in orbit? [Answer is in N]

(b) What was its weight when it was on the Earth's surface, before being launched? [Answer is in N]

(c) While it orbits the Earth, what force does the satellite exert on the Earth?
magnitude [Answer is in N]

    When in orbit, an object is weightless.

    weight on Earth: 360*9.8

    Force: G Me*360/(re+1E7m)^2
