Solid uniform conductiong sphere of mass 'm' and charge Q, rotates about its axis of symmetry with constant angular velocity 'omega' then the ratio of magnetic moment to the moment of inertia of the sphere is (xQomega)/(6m) then x is :(Neglect induced charges due to centrifugal force) |

Answer» Solution :`M=(Q)/(2M)xx(2)/(3)MR^(2).omega` `I=(2mR^(2))/(5)` `(M)/(I)=(5Q.omega)/(6M)`. |
