Question

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 = 10 µC, and Q₃ = -5µC.

(a) Find the electric field at the location of Q₁, due to Q₂ and Q₃.
< ________ , ________ , ________ > N/C

(b) Use the electric field you calculated in part (a) to find the force on Q1.
< ________ , ________ , ________ > N

(c) Find the electric field at location A, due to all three charges.

< ________ , ________ , ________ > N/C

(d) An alpha particle (He²⁺, containing two protons and two neutrons) is released from rest at location A. Use your answer frompart (c) to determine the initial acceleration of the alpha particle.
< ________ , ________ , ________ > (m/s)^2
