Still others may write it as KE1 + PE1 + Eadded to the system = KE2 + PE2 + Eleaving the system. There would be a normal force pointing up and mg pointing down. (b) What is unreasonable about the result? The magnitude of the force on a particle increases as the cube of the distance from that point; that is Fr3 , if the distance from P to the position of the particle is r.
