Two teams play tug-of-war by pulling on a rope stretched between them until one team pulls the other past a mark in the center. One team has especially strong arms. The other team has especially strong legs. If the strong-arm team won, why would they win? Which forces are involved in a tug-of-war? 1. Write your ideas:

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
