Three 1.0 nC charges are placed as shown in FIGURE P22.66. Each of these charges creates an electric field at a point 3.0 cm in front of the middle charge.

Question

Question

a. What are the three fields E1, E2, and E3 created by the three charges? Write your answer for each as a vector in component form.

b. Do you think that electric fields obey a principle of super-position? That is, is there a "net field" at this point given by net

Enet = E1 + E2 + E3? Use what you learned in this chapter and previously in our study of forces to argue why this is or is not true.

c. If it is true, what is Enet?

Answer 1

Answer #1

E = kq / r^2

K = 9×10^9

q = charge

r = distance
