In a certain region, a charge distribution exists that is spherically symmetric but non uniform. That is, the

Solution 88CP Step 1 : Introduction : In this question, we need to derive an expression for electric field E for r aand r a In the second part we need to derive an expression for (r) for r aand r a In the third part we need to show that net charge contained is 0 for r a Condition given 0a2 r 2 r 3 V (r) = 180 × [1 3( )a+ 2( ) ]a for r a V (r) = 0 for r a V And E(r) = r
