a 200 kg rock lies on the surface of a planet. the acceleration due to gravity on the surface of the planet is 6,0. calculate the mass of the planet if it’s radius is 700km

Answer:

4.41×10²²kg

Explanation:

Let the mass of planet be M, rock be m

Therefore,

[tex]net \: force \: on \: rock \: = weight \\ (200)(6) = \frac{(6.67 \times 10 {}^{ – 11})(200)(m) }{(700000) {}^{2} } \\ m = 4.41 \times 10 {}^{22} \: kg[/tex]

Answer:4.41×10²²kgExplanation:Let the mass of planet be M, rock be m

Therefore,

[tex]net \: force \: on \: rock \: = weight \\ (200)(6) = \frac{(6.67 \times 10 {}^{ – 11})(200)(m) }{(700000) {}^{2} } \\ m = 4.41 \times 10 {}^{22} \: kg[/tex]
