Please answer these two questions and explain them step by step. Thank you

A long, nonconducting, solid cylinder of radius 4.1 cm has a nonuniform volume charge density p that is a function of radial distance r from the cylinder axis: p = Arz. For A = 2.3 uC/ms, what is the magnitude of the electric eld at (a) r = 3.0 cm and (b) r = 6.5 cm. e 2. An electric dipole consists of an electron and a proton arranged as shown in the diagram at right. There is a uniform electric field 3 nm E = 150-1. What is the torque acting on the dipole? Express 4 nm your answer in unit-vector form
