Question
Solar energy is incident normally on the earth’s surface at the rate of about 2.2 MW m^{2}. The distance between the earth and the sun is 1.5 × 10^{11} m. Energy (E) and mass (m) are related by Einstein equation E = mc^{2} where c (3 × 10^{8}ms^{1}) is the speed of light in free space. The decrease in the mass of the sun is
