    Field at a point on the axis of a ring with variable charge density

    I just needed help with this part. I felt that the diagram was wrong and hence I got a "wrong" answer (according to the textbook). I did the question thereafter correctly. Thank you for your help :)

    Field at a point on the axis of a ring with variable charge density

    Since it's a ## \cos(x) ## function, so according to the diagram, if they have chosen the following Azimuthal angles, then positive charges must be on the top half and negative on the bottom half here.

    Field at a point on the axis of a ring with variable charge density

    I have great confusion regarding the question after reading the solution from the book. They haven't really correctly done the sign of the charge density if they have taken the angle as follows and the diagram i found a bit vague. Could somebody please help me out here? Thank you :)

    The electric field inside an insulating infinite length solid cylinder

    TL;DR: Suppose there is a cylinder with infinity length and a radius R. At distance R/2, we have to find the electric field present inside. Confirmation needed regarding the method. We are given volumetric charge density as ## \rho ## and we have to find the field at the distance R/2. Is my...
