Two charged particles are placed along the x-axis. The first particle has a charge q, = +q and is at the origin. The second has a charge 92 = -2q and is at x = d = 7.10 cm. (a) Determine the finite value of x (in cm) where the electric field is zero. 17.14 X You may have made a sign error. Think about the magnitude of the electric field due to each charge. Is it possible for the net electric field to be zero on the positive x-axis to the right of the two charges? cm (b) Determine the smallest and largest finite values of x (in cm) where the electric potential is zero. (Note: Assume a reference level of potential V = 0 at r = co.) smallest 0 X value We have three possible regions where the total electric potential could be zero. They are x d. Write an expression for the total electric potential in each region in terms of the distance from q, and the distance between q, and q2. Solve these expressions for the distance from the charge q, . cm largest 2.37 cm value
