Use Newton's Universal Law of Gravitation to calculate the magnitude of the gravitational force between a 200 kg refrigerator and a 70 kg person that is 0.5 meters from the refrigerator.

3.735*10⁻⁶ N

Explanation:

From newton' s law of universal gravitation,

F = Gmm'/r² ... Equation 1

Where F = Gravitational force between the person and the refrigerator, m = mass of the person, m' = mass of the refrigerator, r = distance between the person and the refrigerator. G = gravitational universal constant.

Given: m = 70 kg, m' = 200 kg, r = 0.5 m

Constant: G = 6.67*10⁻¹¹ Nm²/kg².

F = (6.67*10⁻¹¹*70*200) / 0.5²

F = 93380*10⁻¹¹/0.25

F = 373520*10⁻¹¹

F = 3.735*10⁻⁶ N

Hence the force between the person and the refrigerator = 3.735*10⁻⁶ N
