Question

Two infinitely long parallel plates of equal areas, $6$ cm$^2$, are separated by a distance of $1$ cm. While one of the plates has a charge of $+10$ nC and the other has $-10$ nC. The magnitude of the electric field between the plates, if $\varepsilon_0 = \dfrac{10^{-9}{36\pi}$ F/m, is}

• A. $0.6\pi$ kV/m
• B. $6\pi$ kV/m
• C. $600\pi$ kV/m
• D. $60\pi$ V/m
• E. $6\pi$ V/m

Hint:

For parallel plates, $E = \sigma/\varepsilon_0$ and always convert cm$^2$ to m$^2$.
