x L Calculate the potential at point P 0 y Calculate the electric field at P 8 Two rings of radii R and 2R are carrying equal linear charge density and are placed co axially with their centres at a separation R Find the position of the points where the electric field is zero use a graphical solution if necessary Is this a stable equilibrium position for a charged particle placed at this point Discuss the nature of the equilibrium 9 A semicircular ring of radius R is carrying a charge a uniformly distributed over its length Calculate the magnitude
