Q1 of 31 Page 143

How does the force of gravitation between two objects change when the distance between them is reduced to half?

Force between two objects of masses M and m separated by a distance r is given by:

F =


Now according to question,


New distance r' = r/2


So, new force between them F' = 4GMm/r � = 4F


The force increases by factor 4
