Question

What is the magnitude of the gravitational force between a planet and a 6 kg object on its surface? (Mass of the planet is 6 × 1024 kg and radius of the planet is 6 × 106 m.)​

Answer 1

Answer:

mass of object(m)= 6kg

mass of planet (M)= 6*10²⁴kg

Radius of the planet (r)= 6*10⁶m

Hence, magnitude of the gravitational force (F) is given by,

F= G*M*m/ r²

•: 6.67*10-¹¹*6*10²⁴*6/(6*10⁶)² = 66.7 N ( ans).

{gravitational force (G)= 6.67*10-¹¹}
