Show that the electric potential a distance z above the centre of a horizontal circular loop of radius R, which carries a uniform charge density per unit length L, is given by V = LR/2e0 1/(z^2+R^2)^1/2 Obtain an expression for the electrostatic field strength as a function of z.

Solution:
Show that the electric potential a distance z above the centre of a horizontal c
