Chapter 20, Problem 109PP

Predict/Calculate Referring to Example 20-9 Suppose the charge +q at the origin is replaced with a charge +5q, where q = 4.11 × 10^-9 C. The charge −2q is still at x = 1.00 m. (a) Is there a point in the region x < 0 where the electric potential passes through zero? (b) Find the location between x = 0 and x = 1.00 m where the electric potential passes through zero. (c) Find the location in the region x > 1.00 m where the electric potential passes through zero.
