A car runs east to west and another car B of the same mass runs from west to east at the same path along the equator. A precess the track with a force `N_(1)` and B presses the track with a force `N_(2)`. Then

A car runs east to west and another car B of the same mass runs from west to east at the same path along the equator. A presses the track with a force N_(1) and B presses the track with a force N_(2) . Then

A train A runs from east to west and another train B of the same mass runs from west to east at the same path along the equator. A presses the track with a force F_(1) and B presses the track with a force F_(2) . Then

A train A runs from east to west and another train B of the same maas runs from west to east at the same speed along the equator. A presses the track with a force F_1 and B presses the track with a force F2.

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:

A proton beam is fired from west to east and an electron beam is fired parallel to it in the same direction. Force on the electron beam will be
