A train 1 moves from east to west and another train 2 moves from west to east on the equator with equal speeds relative to ground. The ratio of their centripetal accelerations `(a_(1))/(a_(2))` relative to centre of earth is:

Options

A. `gt1`
B. `=1`
C. `lt1`
D. `ge1`

Answer

c

Explanation

The earth rotates west to east. So the velocity of train 2 increases. `a_(c)=v^(2)//R`. Hence centripetal acceleration of train 2 is more.
