    A force of a given magnitude acts on a body. On what factors does the acceleration of the body depend?

    A)  Density of the body

    B)  Volume of the body

    C)  Mass of the body  

    D)  Shape of the body

    Correct Answer: C

    Solution :

     From Newton's second law of motion,             \[F=ma,\,\,a=\frac{F}{M}\] Since, \[F\] is constant,\[a\propto \frac{1}{M}\] For a given magnitude of force, the acceleration produced is inversely proportional to the mass of the body.
