ng. Since the surface of the table is per-fectly smooth and horizontal the weight and the reactionof the plane exactly balance each other. Therefore thepull of the string is the resultant force. Thus the particleis pulled toward the point 0, but somehow manages to keepthe same distance from it; and… … MOTION OF A PARTICLE 105 particle is continually changing, that is, the particle is beingaccelerated. Therefore kinetic reaction manifests itself andacts in a direction opposed to that of the acceleration, thatis, away from the point 0. Hence the pull of the string.But the pull which comes into…
