I unploaded a picture describing this situation

i dont know how to find the Potential difference in this situation
because there is two different objects. a charge and a plane.
on the plane we calculate the Potential difference
E*d=v1-v2
on the charge each potential calculates in V=Q/4pi*e0*r

to different things

please help !


problem description
there is an infinite plane whos charge densety is G

on a distance D we put a positve charge +Q

between this charge and the plane there is two point

A and B
point A is distant from the charge in X

point b is distant from the charge in 0.5X

how do i find the Potential difference
between these point?

to different things

Yes, they're two different things. However, electric potentials obey the property of linear superposition. That means that you can find the potential difference between A and B due to the plane only, and then due to the point charge only, and then add the results.
