The earth and the moon are attracted to each other by gravitational force. Does the earth attract the moon with a force that is greater or smaller or the same as the force with which the moon attracts the earth? Why?
Let m and M be the mass of moon and earth respectively which are separated by a distance r Force of attraction that earth exert on moon, F e = r 2 GMm Force of attraction that moon exert on earth, F m = r 2 GmM Thus earth attracts the moon with same force by which moon attracts the earth. Also the gravitational force is an internal force of attraction between the two bodies, thus they have to be equal
