In order to test the strength of a rope, one end is tied to a large tree and the other end is hitched to a team of $2$ horses. The horse pull as hard as they can, but cannot break the rope. If the rope is untied from the tree and attached to another team of $2$ horses with equal strength, and the two teams pull in opposite directions, the tension in the rope will

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,
$(b)$ just after it is dropped from the window of a train running at a constant velocity of $36 \;km/h$,
$(c)$ just after it is dropped from the window of a train accelerating with $1\; m s^{-2}$,
$(d)$ lying on the floor of a train which is accelerating with $1\; m s^{-2}$, the stone being at rest relative to the train.
Neglect air resistance throughout.

A balloon of mass $M$ is descending at a constant acceleration $\alpha $. When a mass $m$ is released from the balloon it starts rising with the same acceleration $\alpha $. Assuming that its volume does not change, what is the value of $m$ ?
