Problem

A point charge of

+6.0\,\mu\text{C}

is fixed at

x=0

. A second point charge of

+1.5\,\mu\text{C}

is fixed on the

x

-axis at

x=0.40\,\text{m}

. Determine the

x

-coordinate (to the nearest centimetre) at which a small positive test charge would experience zero net electric field along the

x

-axis.
