NCERT Question 1 How does the force of gravitation between two objects change when the distance between them is reduced to half ? We know that Gravitational force between two objects is given by F = πΊππ/π^2 where G = Gravitational constant M = Mass of object 1 m = Mass of object 2 r = Distance between the two objects When distance is reduced to half Distance = π/2 & everything else remains same Thus, New Force = πΊππ/(π/2)^2 = πΊππ/(π^2/4) = 4πΊππ/π^2 = 4 Γ Old Force β΄ When the distance is reduced to half, force becomes four times
