At noon, the sun and earth pull the objects on the earth’s surface in opposite directions. At midnight, the sun and the earth’s pull these objects in same direction. Is the weight of an objects, as measured by a spring balance on the earth’s surface, more at midnight as compared to its weight at noon?

Answer :

The Sun’s gravitational attraction is balanced by the centripetal force of the earth. Hence, the objects on earth don’t feel this attraction. The pull experienced by the objects is thus same during night of day.
