At what distance above and below the surface of the earth a body will have same weight, (take radius of earth as R.)

The weight of a body at the surface of earth is 18 N. The weight of the body at an altitude of 3200 km above the earth's surface is (given, radius of earth Re=6400 km)

The ratio of the weights of a body on Earth’s surface to that on the surface of a planet is 9:4 The mass of the planet is 19th of that of the Earth. If R is the radius of the Earth, what is the radius of the planet? (Take the planets to have the same mass density)

At what altitude above the Earth's surface would your weight be two-thirds of what it is at the Earth's surface?

What will be the weight of a 120kg body if it is taken to 2000km above earth surface?

If R is the radius of the earth and g is the acceleration due to gravity on the earth’s surface, then the density of the earth isa.3g/4πGRb.4g/3πGRc.3G/4gπRd.3gR/4πG
