Two identical trains, at the equator start travelling round the world in opposite directions. They start to-gether, run at the same speed and are on different tracks.
Which train will wear out its wheel treads first?

Solution:-
ReplyDeleteNaturally, the train travelling against the spin of the earth. This train will wear its wheels out more quickly, because the centrifugal force is less on this train.
