Hi, I have find an expression for the Electric Potential of a uniformly charged insulating washer of innner radius a and outer radius b at a point P located a distance z from the washer along the symmetry axis perpendicular to the washer.

I have come up wiht the idea that this problem might be best solved by substracting the Electric Potential (Va) for a disk of radius a from the Electric Potential (Vb) for a disk of radius b.

Or do you see another method?

thank you for your help,

JG

Your method looks good to me.
