An 8x1 multiplexer has inputs A, B, and C connected to the selection inputs S2, S1, and S0, respectively. Its data inputs are as follows: I0 = I7 = 0; I4 = I6 = 1; I2 = I5 = D; I1 = I3 = D’. Determine the Boolean function that the multiplexer implements.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
