Earth is a spherical body, of radius 6,376km, which completes a full rotation about its axis in 24h. How long (in hours) should the day on Earth be so that a person at the equator is able to float freely above the ground? 3.Three lead spheres, of mass 10kg each, are located at three corners of a square of side length 45cm, (figure uploaded below). A bead is released at the forth corner. By considering the gravitational forces among the four objects only, determine the magnitude and direction of the acceleration of the bead when released.
