Problem

A charge of +4 µC is fixed at x = 0 m on the X-axis and a charge of +1 µC is fixed at x = 0.60 m. At which one of the following x-coordinates will a +1 nC test charge experience zero net electrostatic force (consider points only on the X-axis)? a)

x = 0.30\,\text{m}

x = 1.20\,\text{m}

x = 0.40\,\text{m}

x = 0.20\,\text{m}
