Two-point charges are placed on the x-axis. The charge +2q is at x= 1.5 m, and the charge -q is at x = -1.5 m.

(a) There is a point on the x-axis between the two charges where the electric potential is zero. Where is this point?

(b) The electric potential also vanishes in one of the following regions. Identify the appropriate region.
--Region 1: 5.0 m > x > 1.5 m
--Region 2: -1.5 m > x > -3.0 m
--Region 3: -3.5 m > x > -5.0 m

(c) Find the value of x referred to in part (b).
x = __ m
