(a) Consider a uniformly charged, thin-walled, right circular cylindrical shell having total charge $Q$, radius $R$, and length $\ell$,. Determine the electric field at a point a distance $d$ from the right side of the cylinder as shown in Figure. Suggestion: Use the result of Fxample and treat the cylinder as a collection of ring charges. (b) What If? Consider now a solid cylinder with the same dimensions and carrying the same charge, uniformly distributed through its volume. Use the result of disk to find the field it creates at the same point.
