               a.  only gravitational force of the earth acts on it.

               b.  no force including gravitational force acts on it.

               c.  gravitational force and electrostatic force act on it.

               d.  all forces except gravitational force act on it.

                   1.  The value of g on the surface of the earth is                  .
                   2.  The value of g at poles is          than at equator.

                   3.  The value of g is zero at                 .

                   4.  The relation between G and g is given by                       .
                   5.  S.I unit of g is            .

                   1.  Earth attracts apple from the tree, and it falls on it, but the earth does not move

                       towards the apple. Why? (HOTS)
                   2.  A stone and feather are thrown from a tower, both the objects should reach the
