359356 The potential (in volts) of a charge distribution is given by \(V(z) = 30 - 5{z^2}\) for \(|z| \le 1\,m\) \(V(z) = 35 - 10|z|\) for \(|z| \ge 1m\) \(V(z)\) does not depend on \(x\) and \(y\). If this potential is generated by a constant charge per unit volume \({\rho _o},\) (in units of \({\varepsilon _o}\)) which is spread over certain region, then choose the correct statement.

1 \({\rho _o} = 40{\varepsilon _o}\) in the entire region.
