  1. Dc How Did newton guess the inverse rule B B o • Kepler laws A • 1} the orbit of a planet is an ellipse with sun at one of the foci • 2} the line joining the planet and the sun sweep equal areas interval of time • 3} the cube of the mean distance of a planet from the sun is proportional to the square of its orbital period T R3/T2 = constant

  2. Mass of the earth = 6 x 10 24 Kg radius of the earth = 6.4 X !0 6 Gravitational Constant = 6.67 X 10 -11 mass of the object = I kg F =GMm r2 By applying formula of gravitational force F = GMm R2 F = 6.67 x 10 -11 x 6 x 10 24 x 1 ( 6.4 X 10 6)2 By applying formula of gravitational force F = GMm R2 F = 667 x 10 -11 x 6 x 10 24 x 1 x 100 ( 64 X 10 6)2 x 100 4.0 x 10 -4Nm2/kg2
