The figure below shows three charged particles, all lying along the horizontal axis. Particle A, at left, has a 6.05 nC charge. Particle B has a 1.30 nC charge and is 3.00 cm to the right of A. Particle C has a -2.15 nC charge and is 2.00 cm to the right of B. 9 3.00 cm 9B 2.00 cm |---Select--- 9c (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 particle with a charge of -8.00 nC is placed at this point. What are the magnitude (in N) and direction of the net electric force on it? magnitude N direction
