Q. Two cars passing each other at high speed are in danger of side swiping because

Explanation by: Official MCQ Buddy

When two cars pass each other at high speed, the air between them moves faster due to the Bernoulli’s Principle, which states that an increase in the speed of a fluid (in this case, air) results in a decrease in pressure.
As the velocity of air molecules between the cars increases, the air pressure in that space decreases. Meanwhile, the pressure on the outer sides of the cars remains higher. This pressure difference creates a force that pushes the cars toward each other, increasing the risk of a side swipe or collision.
This effect is commonly observed in racing cars, trains, and even in ships passing close to each other.
