Two charges lie on the x axis, +3q at the origin, and -2q at x = 5.0 m. The point on the x axis where the electric potential has a zero value (when the value at infinity is also zero) is
a. 1.0 m. b. 2.0 m. c. 2.5 m. d. 3.0 m. e. 4.0 m.

Explanation:

q1 = 3q at (0,0)

q2 = - 2q at (5, 0)

Let the potential is zero at a distance x from the origin

15 - 3x = 2x

5x = 15

x  = 3 m

Thus, the potential is zero at x = 3 m .

Option (d) is true.
