Mars has a mass of about 6.68 × 10^23kg,and its moon Phobos has a mass of about9 × 10^15kg.If the magnitude of the gravitational forcebetween the two bodies is 4.46 × 10^15N,how far apart are Mars and Phobos? Thevalue of the universal gravitational constantis 6.673 × 10^−11N · m^2/kg^2.Answer in units of m.-Shay. Created by Renee Jones. science-mathematics-en - physics-en

Mars has a mass of about 6.68 × 10^23kg,?

Let,

distance, = d

Mars mass, M = 6.68 × 10^23kg,

Phobos, m = 9 × 10^15kg.

Force, F = 4.46 × 10^15 N

gravitational constant, G = 6.673 × 10^−11 N m^2/kg^2

Since, F = G*M*m / d^2

d^2 = G*M*m / F =

OR,

d^2 = 6.673 × 10^−11*6.68*10^23*9*10^15 / 4.46*10^15 =

= 89.951 x 10^12

OR,

d = 9.484 x 10^6 meters >===================< ANSWER
