Question

What will be the gravitational force between earth and an object of 1 kg. placed on its surface
Here, the mass of earth is 6x1024 kg, and distance from the earth to the earth's surface is 6400 km.​

Answer 1

◆ Answer -

F = 9.77 N

● Explanation -

# Given -

M = 6×10^24 kg

m = 1 kg

R = 6.4×10^6 m

# Solution -

Gravitational force between earth and the object is given by -

F = GMm/R²

F = 6.67×10^-11 × 6x10^24 × 1 / (6.4x10^6)²

F = 9.77 N

Therefore, gravitational force between the earth and an object is 9.77 N.

Hope this helps you...
