(1)A disk of radius R carries a total charge q uniformly distributed over its surface. The disc rotates with a uniform angular velocity about the z-axis (Taken as the axis of rotation). (a) Calculate the magnetic field at some arbitrary point on the z-axis. (b) What is the B-field at the center of the disk?

we can tackle this whenever you are ready.

do you know which law we are going to use to calculate magnetic field from moving charge?

that would be a good start as that will tell us how to begin modelling it.
