I n ordinary weighing scale, in left pan, there is spiral shaped coil (like that mosquito coil) or any long shaped rod. Middle point of this coil is touching the left pan. Let mass of this coil be W1. Second body of mass W2 is attached to other end of this coil. So the left pan is experiencing total weight W1+W2. In right pan, there is mass M3 which mass is equal to W1+W2. So both pans are at same level from ground. Now we remove weight W2 attached to coil. Info regarding removal of weight W2 travels to pan through spiral coil W1 in time t. During this delay t, left pan still experiences total weight W1+W2. If we put weight W2 - which is in our hand - on the left pan during this delay t, then pan will experience total weight W1+W2+W2 which is greater than W3 in right pan. So obviously left pan will come down and right pan will go up during this propagation delay t. That means we have created excess energy and law of conservation of energy is broken. Am I right?
