A parallel plate capacitor of plate dimensions $2 \mathrm{m}\times 2 \mathrm{m}$ is being charged by a current of $2 \mathrm{A}.$ In the region between the plates, the charging current produces a uniform electric field $\overrightarrow{E}$ perpendicular to the plates. The rate of change of the electric field strength with time $\left(\frac{dE}{dt}\right)$ is
