Two people are sitting 3.5 m apart from each other. One person weighs 70.3 kg, and the other weighs 64.5 kg. What is the force of attraction that exists between them?

Question

Quizplus · Accepted Answer

To calculate the force between two objects, use the equation for Newton's Universal Law of Gravitation, which has the form: F = Gm₁m₂/r² Where G is the universal gravitational constant (6.67 x 10-11 N m² kg^-2), m₁ and m₂ are the masses of the two objects, and r is the distance between the objects. Insert the values from the question, and solve for F. F = (6.67 x 10^-11 N m² kg^-2)(70.3 kg)(64.5 kg)/(3.5 m)² F = 2.5 x 10^-8 N
