(adsbygoogle = window.adsbygoogle || []).push({}); Question:

Two charges -2q and +q are located on the z-axis at distance 'd' and '3d' respectively. The x-y plane is a grounded conductor. Find the force on the charge +q.

My work:

Let the force be F. Distance between the charges is '2d'.

[tex]F = \frac{1}{4\pi \epsilon_{0}}\left(\frac{(-2q)(q)}{{(2d)}^2}\right)[/tex]

Can I apply the Coulomb's equation here the way I have done? Will the grounded x-y plane have any effect on the force?
