Question

A charge +q is at the origin. A charge -2q is at x = 4.80 m on the +x axis.
(a) For what finite value of x is the electric field zero?
(b) For what finite values of x is the electric potential zero? (Note: Assume a reference level of potential V = 0 at r = ∞.)
Smallest value of x:
Largest value of x:
Nevermind, figured it out.
