Question

look at the figure and say what is the net force on p? which direction will it mov​

Answer 1

Answer:

(a) Here, m = 0.1 Kg,

a=g=10m/s

2

Net force, F=ma=1N

This force acts vertically downwards.

(b) When the train is running at a constant velocity, its acceleration =0, No force acts on the stone due to this motion.

Therefore, force on the stone F= weight of stone=mg=0.1×10=1.0N

This force also acts vertically downwards.
