Answer:D
A planet with a mass of 5 x 10^24 kg is located 1.5 x 10^11 meters away from a star with a mass of 2 x 10^30 kg. What is the gravitational force between them?
A. 2.22 x 10^11 N B. 2.22 x 10^13 N C. 2.22 x 10^15 N D. 2.22 x 10^17 N
Explanation: F = G(m1*m2)/r^2 = (6.67x10^-11)(5 x 10^24)(2 x 10^30)/((1.5 x 10^11)^2) = 2.22 x 10^17 N
