Given the magnitude and direction of the force acting on a stone of mass 0.1 kg (a) just after it is dropped from the window of a stationary train  (b) just after it is dropped from the window of a train running at a constant velocity of `36 km//hr`  (c) just after it is droped from the window of a train accelerating with `1 ms^(-2)`  (d) lying on the floor of a trin which is accelerating with `1 ms^(-2)` the stone being at rest relative to the train .  Neglect the resistance of air throuhout .
