Two boxes, p and q, are at rest on a frictionless horizontal surface. a light, flexible cord connects them. the mass of p is greater than the mass of q. (as shown in the diagram,) a horizontal force of magnitude f is applied to box q, causing both boxes to accelerate to the right. what best describes the magnitude of the force exerted by the connecting cord on box p? *equal to f *greater than f *zero *less than f, but greater than zero
