Para descobrirmos o valor do campo elétrico, usaremos a fórmula:
![\mathsf{E=K\cdot\dfrac{Q}{d^2}}\\\\
\textsf{Onde:}\\\\
\left\{\begin{array}{cccxc}\mathsf{E=}&?&\rhd&\mathsf{Campo~El\'etrico}\\\mathsf{K=}&\mathsf{9x10^9~Nm^2/C^2}&\rhd&\mathsf{Constante~Eletrost\'atica}\\\mathsf{Q=}&\mathsf{3MC}&\rhd&\mathsf{Carga}\\\mathsf{d=}&\mathsf{3m}&\rhd&\mathsf{Dist\^ancia}\end{array}\right\\\\\\
\mathsf{E=9x10^9\cdot\dfrac{3}{3^2}}\\\\\\
\mathsf{E=\dfrac{9x10^9\cdot3}{9}}\\\\\\
\mathsf{E=\dfrac{27x10^9}{9}}\\\\\\
\boxed{\mathsf{E=3x10^9~N/C=3.000.000.000~N/C}} \mathsf{E=K\cdot\dfrac{Q}{d^2}}\\\\
