A positive point charge q 37times10-5 c is fixed at the, Ask an Expert

Academics

A positive point charge Q = 3.7×10^-5 C is fixed at the origin of coordinates, and a negative charge Q' = -4.1×10^-6 C is fixed to the axis at +3 m. Find the location of the place(s) along the x axis where the electric field due to these two charges is zero.
