In the figure shown, four charges are situated at the corners of a square of side length s. The charges on opposite cor- ners are equal to one another and are labeled Q for corners A and C and labeled q for corners B and D. The charge on Qis positive for all experiments. A 9 D B 9 C ➤X Z (out of page) (a) In a first experiment, it is found that the force on the charge at position C is 0 N. i. Justify the assertion that the charges q cannot have different magnitudes in this experiment. ii. Derive an expression for the magnitude and sign of charge on q in this experiment. (b) In a second experiment, the charge at point C is removed. If the charges q are positive, is there anywhere with- in the boundary square where the electric field could be 0 N/C? (c) The charges are reassembled into their original positions. In a clear, coherent paragraph-length response, ex- plain why the electric field at the center of the square must be 0 N/C regardless of the magnitudes of the charges q or Q and regardless of their signs.
