Answer:
0.0299 N
Explanation:
Applying,
F = Gmm'/r²................... Equation 1
Where F = gravitational force between the boulders, m = mass of the first boulder, m' = mass of the second boulder, r = distance between the boulders, G = Universal constant.
From the question,
Given: m = 7.5×10⁶ kg, m' = 9.2×10⁵ kg, r = 124 m
Constant: G = 6.67×10⁻¹¹ Nm²/kg²
Substitute these values into equation 1
F = (6.67×10⁻¹¹× 7.5×10⁶ × 9.2×10⁵ )/124²
F = (460.23)/15376
F = 0.0299 N
