The Answer of A particle of charge $+ 2 q$ is placed at the origin and particle of charge $- q$ is placed on the $x$-axis at $x$ $= 2 \mathrm { a }$. Where on the $x$-axis can a third positive charge be placed so that the net electric force on it is zero?

A Particle of Charge +2q+ 2 q+2q Is Placed at the Origin and Particle of Charge

A Particle of Charge $+ 2 q$ Is Placed at the Origin and Particle of Charge
