Two identical metal balls are suspended by insulating threads. both balls have the same net charge. in this problem, do not assume the balls are point charges. a. draw a separate free-body diagram for each ball. label the forces to indicate: - the object exerting the force, - the object on which the force is exerted, - the type of force (gravitational, normal, and - whether the force is a contact or a noncontact force. b. suppose the charge on the second ball is reduced slightly, so that it is less than that on the first ball. predict whether the angle that ball l makes with the vertical will be greater than, less than, or equal to the angle that ball 2 makes with the vertical. explain. sketch your answer above. name ball i ball 2 free-body diagram free-body diagram for ball i for ball 2 - - ball i ball 2 how does the free-body diagram for each ball in this case compare to the corresponding freebody diagram that you drew in part a
