As we know that,
Earth rotates from West to East and, in assertion two trains are moving in opposite direction.
∴ The train going towards East will have high speed with respect to earth from the train going rowards West.
∵ Normal reaction is proportional to (speed)2 and speeds of different trains are different. Hence, magnitude of normal reaction is different.
Hence, magnitude of normal reaction is different.
∴ Assertions will be false and reason will be true because their relative speeds are different. But actual speeds of both the trains are same.
