answer parts c and d

A long straight metallic pipe has radius a and surface charge density o. A point located a distance 3a from the axis
of the pipe has been designated as the zero of potential energy.
Part (a) Due to the cylindrical symmetry, the electric field may be expressed as Ē = Erî where is perpendicular to the axis of the pipe. Enter an
expression for the radial component of the electric field, Er, that is valid outside of the pipe, where r > a.
Er = o a/(&or)
V = 01
Part (b) Due to the cylindrical symmetry, the electric field may be expressed as Ē = Erî where is perpendicular to the axis of the pipe. Enter an
expression for the radial component of the electric field, Er, that is valid outside of the pipe, where r <a.
Er = 0
Part (c) Enter an expression for the electric potential, V, that is valid outside of the pipe, where r > a. Recall that a point located a distance 3a from the
axis of the nine has been designated as the zero of potential energy.
V =
Part (d) Enter an expression for the electric potential, V, that is valid inside of the pipe, where r <a.
