Consider a solid sphere of radius r and ...

Consider a solid sphere of radius r and mass m which has charge q distributed uniformly over its volume. The sphere is rotated abut a diameter with an angular speed `omega`. Show that the magnetic moment `mu` and the angular momentum l of the sphere are related as `mu =(q)/(2m) l.`

Text Solution

Verified by Experts

`M/L = ((qomegaa^2)/(4))/((omegama^2)/(2)) = q/(2m)`
