Physics - Electrostatics Question with Solution | TestHub

The potential of the electric field produced by point charge at any point $(x,y,z)$ is given by $\mathrm{V}=3{\mathrm{x}}^2+5$, where $\mathrm{x},\mathrm{y}$ are in metres and $\mathrm{V}$ is in volts. The intensity of the electric field at $(-2,1,0)$ is
