given, charge Q on the cone is uniformly spread over its sloping surface.
 
Let be the surface charge density. the charge on an elementary area of cone of side length dx at a distance x from the apex A[ as shown in figure. ] is given by,
=now the potential at the apex due to this element is given by, 
V = 
now, total charge on the cone is given by, Q = 
so, V = 
 
now, workdone to bring a small test charge q from infinity to the apex of the cone is W = qV =
