A baseball has a mass of 0.145 kilograms, and a bowling ball has a mass of 6.8 kilograms. What is the gravitational force between them if their centers are 0.5 m apart?

1.0 * 10-13 m

1.3 * 10-10 m

2.6 * 10-10 m

1.1 * 10-8 m

We can use the equation for Newton's Law of Gravitation

Fg = (Gm₁m₂) / r²

Where gravitational constant = G = 6.674 x 10⁻¹¹ N · m²/kg²

mass m₁ = 0.145 kg

mass m₂ = 6.8 kg

distance between centers of masses = r = 0.5 m

Substitute these values into ...

Fg = (Gm₁m₂) / r²

Fg = ((6.674 x 10⁻¹¹) (0.145) (6.8)) / (0.5) ²

Fg = 2.63 x 10⁻¹⁰ N

Therefore, your answer should be 2.6 * 10-10
