Question

what is the Gravitational force acting on an object of mass 1 KG on the surface of the Earth​

Answer 1

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
