The figure below shows three small, charged beads, all lying along the horizontal axis. Bead A, at left, has a 6.35 nC charge. Bead B has a 1.30 nC charge and is 3.00 cm to the right of A. Bead C has a -2.15 nC charge and is 2.00 cm to the right of B. 3.00 cm 2.00 cm (a) What is the magnitude (in N/C) of the electric field at a point 2.00 cm to the right of A? N/C (b) A fourth bead with a charge of -2.00 nC is placed at this point. What are the magnitude (in N) and direction of the net electric force on it? magnitude direction N ---Select--- The figure below shows three small, charged beads, all lying along the horizontal axis.
