Field and force with three charges At a particular moment, one negative and two positive charges are located as shown in the gure. 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 eld contributions. and then check the signs of your components against these arrows. LetQ1= 1pC.Q2 = 5pC,andQ3 = -6,uC. (a) Find the electric field at the location of 21, due to @2 and @3. E = N/C Save for Later Attempts: 2 of 10 used Submit Answer Part 2 (b) Use the electric field you calculated in part (a) to find the force on 21. F = N Save for Later Attempts: 0 of 10 used Submit Answer Part 3 (c) Find the electric field at location A, due to all three charges. E = N/C Save for Later Attempts: 0 of 10 used Submit AnswerPart 4 {cl} 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 x 10'27 kg for the mass of He2+.) ' I a= m/s2 Save for Later Attempts: 0 of 10 used
