The electric field in a point on the central axis of a uniformly
charged very thin ring is given by the expression:
E = (k*lambda*2pi*R)/((x^2 +R^2)^(3/2)) i cap
where R is the radius of the ring, lambda is the linear charge
density, and x is the distance of the point on the central axis to
the center of the ring. Use this expression (do not derive it!) to
calculate the field in a point inside a thin shell with uniform...
