A force causes an acceleration of 10 m s-2 in a body of mass 500 g. What acceleration will be caused by the same force in a body of mass 5 kg?

उत्तर
Let the force be F.
Force F causes an acceleration, a = 10 m/s2 in a body of mass, m = 500 g or 0.5 kg
Thus, F = ma
Or, F = (0.5) (10) = 5 N
Let a' be the acceleration which force F (=5N) cause on a body of mass, m' = 5 kg.
Then, a' = F/m'.
Or, a' = (5/5) ms-2.
Or, a' = 1 ms-2.
