Explanation:
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
