WebF = ( G m M) r 2. Where G is the gravitational constant and r is the distance between the bodies. a. Find d F d r and explain what it means. b. Suppose that it is known that the Earth attracts an object with a force that decreases at the rate of 2 N/km when r = 20,000km. How fast does this force change when r = 10,000km? Part a: Derivative is d ... Web13 mrt. 2024 · Example 2: Derive an expression for the amount of work done to move a body from the Earth’s surface to infinity i.e. beyond Earth’s gravitational field. Solution: We know Work done (W) = Force × displacement. But we cannot use this formula directly because gravitational force is not constant.
