+6.0\,\mu\text{C}

charge is fixed at

x = 0

and a

-2.0\,\mu\text{C}

charge is fixed at

x = 0.50\,\text{m}

on a straight line. At what position on the

x

-axis (other than at infinity) can a

+1.0\,\mu\text{C}

test charge be placed so that the net electrostatic force on it is zero? Give the coordinate

x

in meters relative to the origin.
