Imagine a universe that has a permitivity of ε = 3εo. Withinthis infinite space, you find a spherical distribution of charge ofradius a that has a volumetric charge density of Ïv = ( a r ) Cm−3. a. Determine the expressions for the electric field inside andoutside this spherical region. b. Determine an equation thatrepresents the energy required to put together this distribution ofcharge. c. If a = 2 m, what is this energy equal to in Joules?
