Answers and Explanation:
The step by step explanation is clearly screenshot in the two attachments below for easy understanding.
NOTE:
A uniform charged solid sphere of radius R carries a total charge Q, it therefore has its charge density as Q/(4/3ΠR³). And to find magnetic moment of a sphere, the sphere has to be divided into infinitesimal charges.
Magnetic Dipole Moment of the sphere would be given as 1/5QwR²z
