    The potential (in volts ) of a charge distribution is given by

    $V(z)\, = \,30 - 5{z^2}for\,\left| z \right| \le 1\,m$

    $V(z)\, = \,35 - 10\,\left| z \right|for\,\left| z \right| \ge 1\,m$

    $V(z)$  does not depend on $x$  and  $y.$  If this potential is generated by a constant charge per unit volume $\rho _0$ (in units of $\varepsilon _0$ ) which is spread over a certain region, then choose the correct statement
