Consider a solid, rigid spherical shell with a thickness of 100 mm and a density of 3900 kg/m3kg/m3. The sphere is centered around the sun so that its inner surface is at a distance of 1. 50×1011 mm from the center of the sun. What is the net force that the sun would exert on such a dyson sphere were it to get displaced off-center by some small amount? express your answer numerically in newtons.
