Astatic electric field with spherical symmetry is described by , where c and r are constants. rcre r, where e and r are constants. (a) determine the charge density, p(r). [8 points (b) find the total charge of the system. [8 points] (c) find the static electric potential v(r). [8 points] (d) find the total energy stored in the electric field. [8 points] (e) a small test charge +q is released at rest at the radial location r r. what is the kinetic energy when it reaches a point far away?
