@angel13061987 The electric field just past the point a is inside the conductor, and the E field inside a conductor is zero, ( the formula for electric field inside the cavity isn't valid at this point because it was derived with a gaussian surface with r<a.)

Thanks for the video.

I think there is a mistake at 6:05.

The field inside the cavity does not fall all the way to zero (because it cant go to infinity but can only go as far as α)

Magnificent video, very instructive.
