1) A long thin rod is placed along the axis of a long cylindrical shell of radiuses of R. If the linear charge density of the thin rod is it > 0 and the surface charge density of the cylinder is 0' > 0. Find the electric filed for inside and outside the cylinder. Fig 1. Problem 1 2) The center of a spherical conductor with radius R and charge of q > 0 is located at x = U, a point charge with charge of q is placed on x-axis at x = 4R. Find the electric led and potential at point A on x-axis at x = 2R. Find the acceleration of a particle with mass m and charge q that is placed at rest at point A. What is the velocity of the particle that is started from rest at point A when it gets to point B on x-axis at x = 3R
