Question

[Physics: Electricity & Magnetism]

If anyone knows anything about electric fields and Gauss's Law for Electricity, please help! The question is posted below.

Answer 1

Consider an infinite conducting plane at the surface x=0. If a charge +Q is placed at \[r _{1}=<d,0,0>\]and a charge -Q is placed at \[r _{2}=<d,a,0>\]Find the force on the negative charge.

Answer 2

The net force on the negative charge will be a combination of the force on -Q due to the infinite plane as well as the force on -Q due to the +Q.

You can use Gauss's law to derive an expression for the infinite conducting plane and its electric field. For +Q, you can just use Coulomb's Law to figure out the force.
