it is advised not to stand near a running train.why?
when the train is moving with a very high speed, the velocity of air around increase and according to bernoulli's principle, we know that as velocity increases the pressure decreases. which means the region where we will b standing is of high pressure as compared to that of train(higher the velocity lower the pressure). hence we will be pulled towards it where the chances of getting injured is really very high. Hope my answer has helpes u. if u r satisfied please giv me thumbs up
