A boy with a mass of 55 kg walks into a room and sees a girl 8.0 m in front of him who has a mass of 40 kg. What is his gravitational attraction to her?

Question

Quizplus · Accepted Answer

The formula for gravitational attraction is F = G(m1*m2)/d^2, where F is force, G is the gravitational constant (6.67 x 10^-11 Nm^2/kg^2), m1 and m2 are the masses of the objects, and d is the distance between them. Plugging in the given values, we get F = (6.67 x 10^-11)(55)(40)/(8^2) = 2.3 x 10^-9 N, which is closest to option B.
