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. Normal force by the track on train A is $N_1$ and that on train B is $N_2$

• A. $N_1>N_2$
• B. $N_1<N_2$
• C. $N_1=N_2$
• D. the information is insufficient to find the relation between $N_1$ and $N_2$

Answer 1

Answer: (A)

$N_1>N_2$

Gravity is least at the equator, hence the normal reaction would also be the least at such a point.
Hence
$N_1>N_2$
Option A is correct.
