8. Three identical point charges q are placed at each of three corners of a square of side L. A) Find the magnitude of the net force on a point charge -3q placed at the center of the square. Express your answer in terms of variables ‘q’ ‘L’ and constant ‘k’. B) Find the magnitude of the net force on a point charge -3q placed at the vacant corner of the square. Express your answer in terms of variables ‘q’ ‘L’ and constant ‘k’.

3. A hollow, conducting sphere is initially uncharged. A positive charge, +9₁, is placed inside the sphere, as shown in the figure below. Then, a second positive charge, +q2, is placed near the sphere but outside it. Which of the following statements describes the net electric force on each charge? +9₂ A. There is a net electric force on +91 but not on +92. B. Both charges are acted on by a net electric force with the same magnitude and in the same direction. C. Both charges are acted on by a net electric force with the same magnitude but in opposite directions. D. There is a net electric force on +q2 but not on +9₁.

b) Calculate the net force (magnitude and direction) exerted on charge q by the other four charges, in terms of q, Q, d, and e0. You may draw the force vector to indicate the direction. c) If the charge q is released from rest, and the four other charges held fixed, will the charge q ever “escape” to infinitely far away (assuming an infinite amount of time can pass)? Justify your answer.
