a) Find the surface charge density σ2 of the cylindrical shell of radius R2. (Note the unit in the input box and the sign of charges.)
Give your answer up to at least three significance digits.
b) Find an expression of electric field at rmm from the center where R1<r<R2. Assume the cylinder has a length L and L is very long so that electric field is uniform. Consider that the insulating material between the cylinders is air. (Hint : use Gauss's law and cylindrical Gaussian surface with radius r.)
Give your answer up to at least three significance digits.
c) Calculate absolute value of the potential difference between the wire and the cylinder.
Give your answer up to at least three significance digits.
d) Calculate the capacitance C for this cylindrical system. Assume that the length of the cylinder is L=17cm.
Give your answer up to at least three significance digits.
