4. (12 points) The figure shows a long non-conducting massless rod of length L pivoted at its center. At the left and right ends of the rod are attached small point charges :- with charges q and Eq respectively. A distance h directly beneath each of these charges is a fixed sphere with positive charge Q. A block of weight W is placed to the right of the pivot bearing in order to balance the rod and 4"! Bt'l'i ng keep it horizontal. The pivot bearing shown exerts a force FN on the rod. The followim values are given: q = 2 x 1096, Q = 8 x 1096, L = 1m. W = 0.72M. and h = 1 x 10%. I: Complete the table below. Where the value is not given or cannot be calculated beforehand, u5e an appropriate symbol for the magnitude. Force directions should be listed either as \"+" or \"-" along the y- axis. Torque directions are either \"+" for counterclockwiSe rotations or \"-\" for clockwise rotations. Take the axis of rotation to be at the pivot bearim. which is shown at the center of the rod. Force Magnitude of Direction of Lever- Magnitude and direction of force (N) force (+ or -} Arm (In) Torque (4- or -) Force of Q on q Weight of rod. W Normal Force, FN II: Using the torque condition for equilibrium: 1m 2 0 and IN = chw. calculate the distance x from the bearing at which the weight W should be located in order to balance the rod.
