An infinitely long cylindrical object with radius R has a charge distribution that depends upon distance r from it's axis like this : ρ=ar+br2(r≤R, a and b are non zero constant, ρ is volume charge density). If electric field of the cylinder is zero , then the value of ab is −nR4 where the value of n (upto two decimal places) is |
