Document Summary

In a similar manner, the charge can be distributed over a surface s of area a with surface charge density s, Then, the total amount of charge in the surface s can be written as, If the charge is distributed over a line of length l, then the linear charge density l is, Then, the total amount of charge over the line can be written as, If the charge is distributed uniformly, the charge density is independent of position: charge volume density, charge area density, charge linear density. The radius of the ring is r. the observe point o lies on the axis of the ring. The total charge of the ring is q.
