Q5.3 Give the magnitude and direction of the net force acting on a stone of mass 0.1 kg,

(a) just after it is dropped from the window of a stationary train, Neglect air resistance throughout.

Answers (1)


Since the train is stationary so the net force acting on the stone is the gravitational force which acts in the downward direction.

Gravitational force :

                                              F\ =\ ma\ =\ mg

or                                                                  =\ (0.1)10

or                                                                  =\ 1\ N
