               MCQ(BOARD)
               1.  A body of mass 1kg is attracted by the earth with a force which is equal to
                   a.  9.8N
                   b. 6.67x 10 11
                   c.  1 N
                   d.  9.8m/s
               2.  The mass of the body on moon is 40kg, what is the weight on the earth.

                   a.  240kg
                   b.  392N
                   c.  240N
                   d.  400kg
               3.The value of ‘g’

                   a.  Increases as we go above the earth’s surface
                   b.  Decreases as we go to the center of the earth
                   c.  Remains constant
                   d.  Is more at equator and less at poles
               4.The ball is thrown up, the value of ‘g’ will be

                   a.  Zero
                   b.  positive
                   c.  negative
                   d.  negligible
               5. The mass of an object is 12 kg on the earth. The mass of the same object on the
               moon will be

               a.  2 kg.
               b.  10 kg.

               c.  12 kg.

               d.  16 kg.



               6. Suppose the earth began to shrink without any change in its mass, will there be any
               change in the value of acceleration due to gravity.
               a.  yes
               b.  no
               c.  cannot be determined
