(a) Find the electric field at x = 5.00 cm in Figure 18.48(a), given that q = 1.00 μC.

(b) At what position between 3.00 and 8.00 cm is the total electric field the same as that for-2q alone?

(c) Can the electric field be zero anywhere between 0.00 and 8.00 cm? 

(d) At very large positive or negative values of x, the electric field approaches zero in both (a) and (b). In which does it most rapidly approach zero and why? 

(e) At what position to the right of 11.0 cm is the total electric field zero, other than at infinity?
