    If the mass of a body and the force acting on it are both doubled, what happens to the acceleration?

    A) doubled                                    

    B) halved

    C) remains same                            

    D) becomes zero

    Correct Answer: C

    Solution :

    [c] We know that acceleration is related to mass by the expression, \[a=\frac{F}{m}\] Now, if both force and mass are doubled, acceleration \[{{a}_{1}}=\frac{2F}{2m}\], i.e. acceleration will remain the same.
