Solve the problem.Newton's Universal Law of Gravitation states that the attractive force exerted on one spherically symmetric object of mass M by a second spherically symmetric object of mass m is given by 
where r is the distance between the centers of the two objects and G is a constant equal to 
when F is in newtons (N), M and m are in kilograms (kg), and r is in meters (m). What is the magnitude of the gravitational force exerted on an object of mass 1 kg by an object of mass 10 kg if the objects are 1 m apart?
