Question

The mass of the earth is 6×10^24 kg and it's your mass is 40kg find the force of attraction between you and the earth

Answer 1

Answer:

F = 39.1×10^12

Explanation:

Force of attraction between the earth and the object on its surface

F = GMm

r^2

G= gravitational constant

6.674×10^-11 N ( m/kg)^2

M= mass of earth

m= mass of object ( in this your mass)

r = separation(radius of earth from its centre to object)

So,

F= 6.674×10^-11×6×10^24×40

(6.4×10^6)^2

F= 6.674×10^-11×6×10^24×40

6.4 ×6.4×10^12

F = 6.674×6 ×10^12×40

40.96

F= 10011× 10^12

256

F = 39.1×10^12
