What is (4NBA)/T suppose to mean? Peak? RMS? Half-cycle average?

Even if the generator had a rectified output, the average fem wouldn't match your notes. Can you check them?

I've tried several programs but I've never been able to "write" equations fast enough. My old hand always wins.

The electric field at P must be a vector. Post #16 gives the (wrong) modulus of the electric field at P as a function of the distance "y" along the plane.

The OP says we have half planes and that P lies at the edge of the half plane. We can't use results valid for an infinite distribution.

From your drawing I see that y/h=tan(theta) thus y=h tan(theta)

I don't have Krotov's book but I'm sure problem 3.12 is an example of the method of images. Your case Is different and requieres integration.

From your post I conclude you assumed the planes perform like point charges. I think it's wrong

k makes things worse. Choose a reference system such that "a" carries the right sign

What did Archimedes say?

Try to write Biot's law for just one quarter but do not integrate yet.

You haven't how current flows. Anyway, the B's can't lie on the plane

Please, show us your attempt.

The region where a laser beam is almost parallel is known as the Rayleigh range and it depends on the wavelength a beam "radius" w0. We need that data to help you.

Please, show us your method.
