Answer 1

Answer:

What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface?

(Mass of the earth is 6 × 1024 kg and radius of the earth is 6.4 × 106 m.)

Answer:

Given:

Mass of earth m1 =6 × 1024 kg

Mass of the object m2 = 1 kg

Radius of the earth =6.4 × 106 m

Universal gravitational constant G = 6.67 x 10-11 Nm2kg-2

By applying universal law of gravitation: - F = (G m1 m2/r2)

= (6.67 x 10-11 x 6 × 1024 x 1)/ (6.4 × 106)2

F = 9.8 N
