Answer:
13 N
Explanation:
The Net Force of an object should be the difference between the forces applied to the object if the object is not in equilibrium. This object is not in equilibrium so therefore by finding the difference between the forces, you will find your answer. 20 N - 7 N = 13 N.
Answer:
Explanation:
Given
Train travels towards south with a velocity if 
Rain makes an angle of 
with vertical
If an observer sees the drop fall perfectly vertical i.e. horizontal component of rain velocity is equal to train velocity
suppose 
is the velocity of rain with respect to ground then
Therefore velocity of rain drops is 27.36 m/s
