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 = ๐บ๐๐/๐^2 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 = ๐/2 & everything else remains same Thus, New Force = ๐บ๐๐/(๐/2)^2 = ๐บ๐๐/(๐^2/4) = 4๐บ๐๐/๐^2 = 4 ร Old Force โด When the distance is reduced to half, force becomes four times
