  • question_answer
    Two balls of same size but the density of one is greater than that of the other are dropped from the same height, then which ball will reach the earth first (air resistance is negligible)                            [J & K CET 2004]           

    A)                         Heavy ball                  

    B)                         Light ball            

    C)                         Both simultaneously                

    D)                         Will depend upon the density of the balls

    Correct Answer: C

    Solution :

                                Since acceleration due to gravity is independent of mass, hence time is also independent of mass             (or density) of object.
