+5.0\,\mu\text{C}

charge is fixed at the origin and a

+3.0\,\mu\text{C}

charge is fixed on the

x

-axis at

x = -0.20\,\text{m}

. A third point charge

q

is placed on the

x

-axis at

x = +0.30\,\text{m}

such that the net electrostatic force on the charge at the origin is zero. Determine the magnitude and sign of

q
