Question

Suppose that two objects attract each other with a gravitational force of 50N. If the mass

of both objects was tripled, and if the distance between the objects was doubled, then what
would be the new force of attraction between the two objects?

Answer 1

112.5 N

Step-by-step explanation:

50 = GMm/r^2

Let F be the new force of attraction

F/50 = ( G(3M)(3m)/(2r)^2 ) / (GMm/r^2)

[Elimiating G,M,m,r]

F = 112.5 N
