Gravity Numerical Class-10 Formula 1. F = Gm 1 m 2 /d 2 F = GMm/R 2 2. g = GM/R 2 g’ = GM/(R+h) 2 3. g/g’ = (R+h) 2 /R 2 g a 1/R 2 4. F = mg 5. F a m 1 m 2 F a 1/R 2 1. What is the change in the gravitational force between two bodies if the distance between the centre of them is halved, keeping their masses constant? Calculate. 2. Find out the change in gravitational force between two bodies of fixed mass, when placed at double distance. 3. What change occurs in the gravitational force between two bodies when mass of each is made doubled and distance between their centers is halved? Calculate. 4. How does the gravitational force between two bodies change if the distance between them is tripled? Calculate. 5. T
