QA = QB = 1.5 C, and QC = −3.0 C are located as shown in the diagram. a) Calculate the electric field from charges B and C at the location of point A. In other words, you may want to start by redrawing the diagram with charge A replaced by point P. Draw the electric field contributions from B and C at that point. b) What is the net electric force on QA?

Field and force with three charges At a particular moment, one negative and two positive charges are located as shown in the figure. Your answers to each part of this problem should be vectors. It helps a great deal to make a diagram with arrows representing the various electric field contributions, and then check the signs of your components against these arrows. Let Q1 = 1 μC, Q2 = 7 μC, and Q3 = −5 μC. (a) Find the electric field at the location of Q1, due to Q2 and Q3. E→ = N/C (b) Use the electric field you calculated in part (a) to find the force on Q1. F→ = N (c) Find the electric field at location A, due to all three charges. E→ = N/C (d) An alpha particle (He2+, containing two protons and two neutrons) is released from rest at location A. Use your answer from part (c) to determine the initial acceleration of the alpha particle. (Use 6.646×10−27 kg for the mass of He2+.) a→ = m/s2
