Question

What is the force of gravity between
earth and mass of 1kg placed on
its surface ? mass of earth
(G = 6.67X10^11 Nm^2/kg^2)​

Answer 1

Answer:

Where: mass, m, is 1 kilogram; mass of the Earth, M, is 6.0 × 10 24 kilogram; the radius of the Earth (separation of masses), r, is 6.4 × 10 6 m; and G is 6.67 × 10 -11 newton square metrekilogram-2}. Inserting these values into the equation, and work this out to get a force of 9.8 newton .
