Question: Suppose we have four orange conductor-coated pith balls A, B, C, and D suspended on non-conducting threads. The charge states of all four balls

Suppose we have four orange conductor-coated pith balls A, B, C, and D suspended on non-conducting threads.

Suppose we have four orange conductor-coated pith balls A, B, C, and D suspended on non-conducting threads. The charge states of all four balls are unknown. We bring the alls near each other (without contact) two by two. The interactions are as follows: (1) A is attracted to B and C; . (2) B is attracted to A, C and D; (3) C and D are repelled from each other. > What are the charge states of A, B, C, and D? Explain your reasoning. B D
