1. The problem statement, all variables and given/known data A 100 gram mass is hanging vertically from a spring scale and exerts a certain force. Another 100 gram mass is set up in the following situation (there is a pulley, spring scale, mass, and ring stand holding up the spring scale): Do the weights on each setup exert equal forces on the spring scale, neglecting the weight and friction of the pulleys? 2. Relevant equations 3. The attempt at a solution I thought that I would have to separate the second one in to vectors to figure out if there is a difference.
