The rotation of the earth causes a centrifugal effect on a mass near the surface of the earth.This slightly changes the effective acceleration due to gravity. We can call the oldacceleration due to gravity go and the effective acceleration geff:a. Show that the angle between go and geff can be expressed as2R sin(0) cos(e)\P = tan-19o - Ns/s,R sin2 (0)where e is the angle between the angular velocity of earth and the position of themass near the surface of the earth.b. How small that o if e is 45° and R is the radius of the earth.Ns/SomTm/S
