Question

Romeo and Juliet are sitting on a balcony 1.2 meters apart. If Romeo has

a mass of 69.3 kg and Juliet has a mass of 52.0 kg, what is the attractive
force between them?

Answer 1

F = G M.m/r²

F = force, N

G = gravitational constant, 6.67 x 10⁻¹¹ Nm²/kg²

m,M = mass of object, kg

r = distance, m

F = 6.67 x 10⁻¹¹ x 69.3 x 52/1.2²

F = 1.669 x 10⁻⁷
