Question

Determine the gravitational force of attraction between the Earth and the Sun given the mass of the earth is 6 x 10^24 kg, the mass of sun is 2 x 10^30 kg and the average distance is about 1.5 x 10^11 m. Use scientific notation for final result.

Answer 1

35.57*10^21 N.

Step-by-step explanation:

F = Gmm/r², where G is 6.67*10e-11 & r is distance.

F = 6.67*10^-11 * 6*10^24 *2*10^30 /(1.5*10^11)².

F = 35.57*10^21 newtons.
