    The earth's gravitational force causes an acceleration of 5 \[m{{s}^{-2}}\]in a 1 kg mass somewhere space. How much will the acceleration of a 3 kg mass be at the same place?

    A) 5 \[\,m{{s}^{-2}}\]      

    B) \[\,\frac{3}{5}m{{s}^{-2}}\]

    C) \[\,\frac{9.8}{5}m{{s}^{-2}}\]                         

    D) Zero

    Correct Answer: A

    Solution :

    [a] The acceleration produced in any body due to the gravitational pull of the earth does not depend on the mass of the body. So, the acceleration produced in the 3 kg mass will also be 5 ms-2.
