Newton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass m on a body of mass M is GmM F = where G is the gravitational constant and r is the distance between the bodies. (a) Find dF/dr. dF dr = X What is the meaning of dF/dr? O dF/dr represents the rate of change of the distance between the bodies with respect to the force. O dF/dr represents the rate of change of the force with respect to the distance between the bodies. O dF/dr represents the rate of change of the mass with respect to the force. O dF/dr represents the rate of change of the mass with respect to the distance between the bodies. O dF/dr represents the amount of force per distance. What does the minus sign indicate? O The minus sign indicates that the bodies are being forced in the negative direction. O The minus sign indicates that as the distance between the bodies decreases, the magnitude of the force remains constant. O The minus sign indicates that the force between the bodies is decreasing. O The minus sign indicates that as the distance between the bodies increases, the magnitude of the force increases. O The minus sign indicates that as the distance between the bodies increases, the magnitude of the force decreases. (b) Suppose it is known that the earth attracts an object with a force that decreases at the rate of 4 N/km when r = 20,000 km. How fast does this force change when r = 10,000 km? X N/km
