a 100-kg object and a 400-kg object are separated by a distance d. Find the magnitude of the net gravitational force exerted by these objects on a 60.0-kg object placed midway between them. At what positions can the 60 kg object be placed so as to experience a net force of zero from the other two objects

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
