I have a question regarding charged particles, it is as follows: A charge +q is at the origin. A charge -2q is at x = 9.00 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:.
