The potential (in volts) of a charge distribution is given by V(z)=30−5z^2 for |z|≤1m V(z)=35−10|z| for |z|≥1m. V(z) does not depend on x and y. If this potential is generated by a constant charge per unit volume ρ0 (in units of ϵ0) which is spread over a certain region, then choose the correct statement.
