Answer Key : (d) -

(d)

Since, earth from west to east, so train  has effectively more angular velocity in comparison to train  and hence, experiences a greater centrifugal force directed radially outwards. So, train  will exert a lesser force on track  in comparison to train . Hence,  exerts greater force on track
