can someone help me on this? thanks in advance:(adsbygoogle = window.adsbygoogle || []).push({});

A positive charge +2q lies on the x-axis at x=-a and a charge -q at x=+a. Find a point where the electric force on the third charge Q would be zero.

should i continue on using Coulomb's Law, and just use arbitrary variables or is there another waY? thanks :tongue: :surprised
