Q Find the V Eq" between radius C and d at r radius If Vat r=C is v1 and v at r=d is V2 given { For homogeneous medium } Sel Pr=0,so take L.E + in spherical co-or sys i.e 1/2 r2 av consider only Vis the fun of r only Integrate both sides:- r2 dv = 0+1 A av = A or 82 Integrate once again => V= -A + B - 1 V=V1 at r= c and v= V2 at r=d v==A.B - t solve for A and B c A= (v,-v2)cd & B= VIC-V2d V2 = - A + B c-d c-d d V= r c-d v2)cd + c-d vic-v2d V = (v,-v2)cd + V2d-v,c Is (d-c)r d-c Current density 3 = Ja r3 az is given find cylinder Ju.(M) = H.(2Ar) = J.
