question_answer1) The potential (in volts) of a charge distribution is given by \[V(z)=30-5{{z}^{2}}\]for\[|z|\le 1m\] \[V(z)=35-10|z|\]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 \[{{\rho }_{0}},\](in units of \[{{\varepsilon }_{0}}\]) which is spread over certain region ,then choose the correct statement.
