Question

A train 'A' runs from east to west and another train 'B' of the same mass runs from west to east at the same speed along the equator. 'A' presses the track with a force F1 and 'B' presses the track with a force F2 .
(a) F1 > F2
(b) F1 < F2
(c) F1 = F2
(d) The information is insufficient to find the relation between F1 and F2 .

Answer 1

We know that the Direction of the motion of the Earth is along the west to east. Now there will be the centripetal force which will increase the motion of the object which will be moving in this direction.

On the Other hand it will decrease the Normal force of the Object moving in opposite direction.

In comparison to the question,  ''A'' Train moves along East to west as a result its Normal Force will increase whereas ''B'' Train moves West to east, as result its Normal Force will decrease.

Therefore,  Train A, will push the track more in comparison to Train B.

∴ F₁  > F₂

Therefore, Correct answer will be Option (a).

Hope it helps.
