A train of mass m moves with a velocity v on the equator from east to west. If ω is the angular speed of earth about its axis and R is the radius of the earth then the normal reaction acting on the train is

if the earth stops spinning about its axis? assumes the earth to be a sphere of radius 6.4 x 10^6m. what will be the change in the value of g at a place whose latitude is 45degree
