(b) 4 times

               (c) 1/2 times

               (d) Unchanged

               5. The distance between two bodies becomes 6 times more than the usual distance. The
               F becomes

               (a) 36 times

               (b) 12 times

               (c) 1/36 times

               (d) Unchanged

               6. The gravitational force between two objects is f. If masses of both the objects are
               halved without altering the distance between them, then the gravitational force would
               become

                   (a)  f/4
                   (b)  f/2
                   (c)  f
                   (d)  2f

               7. The expression for finding the gravitational force of attraction between any two bodies
               is

               (a) F= Gm1 m2/r
                                2
               (b) F= Gm1 m2/r
                             2
               (c) F= Gm1 /r
                                3
               (d) F= Gm1 m2/r

               8. If the distance between objects decreases, then the gravitational force between the
               objects will:

               (a) decrease
               (b) Increase
               (c) remain same
               (d) none of the above

                                                       SUBJECTIVE
               1. 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
