The weight of an object at the surface of a planet is proportional to the planet's mass and inversely proportional to the square of the
radius of the planet. Jupiter's radius is 11 times Earth's, and its mass is 320 times Earth's. An apple weighs 2.70 N on Earth. How much
would it weigh on Jupiter?
