Two free point charges +q and +4q are spaced apart by a distance L. A third charge is then placed in such a way that the entire system is in equilibrium. a) Determine the position, magnitude and sign of the third charge.b) Show that the balance is unstable.

There are 3 thin conductive infinitly thin spherical shells with a charge on each shell of +2Q. The innermost shell has a radius of R. Another of the shells has a radius of 2R. The outermost shell has a radius of 3R.  Draw a graph of E vs R. Make sure to show the values of E(3R), E(2R), and E(R).  Note: (put R on the x axis)

charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are 91 = 6.50 uC, 92 = 1.17 uC, and 93 = -1.79 uC. Marble 9p is a distance r1 = 3.00 cm to the left of the marble 92, while marble 93 is a distance r3 = 2.00 cm to the right of the marble 92, as shown. Calculate the magnitude of the electric field a distance r' = 1.00 cm to the left of the center marble.———-N/C Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of 3.71 MC, calculate magnitude and direction of the force on it. magnitude direction—-
