Asatellite of mars, called phobos, has an orbital radius of 9.4 ✕ 106 m and a period of 2.8 ✕ 104 s. assuming the orbit is circular, determine the mass of mars. (kg)

Explanation:

assume

M= mass of Mars

m=mass of phobos

r=orbital radius

T=period

we can apply F=ma to this orbital motion (considering the cricular motion laws)

where,

 and a=rω^2

where ω= and G is the universal gravitational constant.

G = 6.67 x 10-11 N m2 / kg2

i think if it were me i whould divide 300 dide 15
