Effect on gravitation acceleration due to rotation of earth and orbital motion

State the expression for the effective gravitational acceleration due to the rotational of the Earth at a latitude lamda on the Earth's surface.

Two satellites of identical masses orbit the Earth at different heights. The ratio of their distance from the centre of earth is d : 1 and the ratio of the acceleration due to gravity at those heights is g : 1. Then the ratio of their orbital velocities is ________ .

The orbital velocity for an earth satellite near the surface of the earth is 8 km/sec. If the radius of the orbit is 4 times the radius of the earth, its orbital velocity will be

The acceleration due to gravity at the latitude 45^(@) on the earth becomes zero if the angular velocity of rotation of the earth is

If g is acceleration due to gravity at the equator when earth were at rest and g_(1) is acceleration due to gravity at the same place when earth spins with angular velocity omega, the relation between them is
