The potential (in volts) of a charge distribution is given by V(z)=30-5z^(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 potential is generated by a constant charge per unit volume rho_(0) (in units of in_(0)) which is spread over a certain region, then choose the correct statement.

The potential (in volts) of a charge distribution is given by V(z)=30

1.	The potential (in volts) of a charge distribution is given by V(z)=30-5z^(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 potential is generated by a constant charge per unit volume rho_(0) (in units of in_(0)) which is spread over a certain region, then choose the correct statement.
Answer» `rho_(0)=20 in_(0)` in the entire redion `rho_(0)=10 in_(0)` for `\|z\| le 1m` and `rho_(0)=0` ELSEWHERE `rho_(0)=40 in_(0)` in the entire REGION `rho_(0)=20 in_(0)` for `\|z\| le 1m` and `rho_(0)=0` elsewhere Answer :B
