Two point charges Q1, and Q2 are place exactly on the x axis at -x1. A second particle Q2 is placed at +x2 on the positive x axis. 1) Find the electric field due to Q1 at the origin. 2) The electric field due to Q2 at the origin What is the total E field at the origin? If the total E field at the origin is 0 find Q2 in terms of Q1
