Newton was holding an apple of mass 273 g and thinking about the gravitational forces exerted on the apple by himself and by the Sun.  Calculate the magnitude of the gravitational force acting on the apple due to the Sun. (You may enter your calculation using scientific notation.) (Take the mass of the Sun to be 1.99 × 1030 kg1.99 × 1030 kg and the distance from the Sun to be 149.6 × 109 m149.6 × 109 m .)
