3. 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 × 106m).

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

Answer:

F = G mm/R²

F = (6.67 X 10^-11 X 6 X 10²⁴ X 1)/(6.4 X 10⁶)²

F = 9.8 N
