In Fig., two positive charges q₂ and q₃ fixed along the y axis, exert a net electric force in the + x direction on a charge q₁ fixed along the x axis. If a positive charge Q is added at (x, 0), the force on q

Options:
(a) shall increase along the positive x-axis.
(b) shall decrease along the positive x-axis.
(c) shall point along the negative x-axis.
