Question

What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6×10 24 kg and radius of the earth is 6.4×10 6 m.)

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.
