(a) Twelve equal charges, q, are situated at the corners of a regular twelve-sided polygon (for instance, one on each numeral of a clock face). What is the net force on a test charge Q at the center? (b) Suppose one of the 12 q charges is removed (the one at "6 o'clock"). What is the force on Q? Explain your reasoning carefully. (c) Now let 13 equal charges, q, be situated at the corners of a regular 13-sided polygon. What is the force on a test charge Q at the center? (d) If one of the 13 q charges is removed, what is the force on Q? Explain your reasoning.
