F= \frac{K_{0}.|Q_{1}||Q_{2}|}{d^{2}}

5,7= \frac{(9.10^{9}).(26.10^{-6}).(47.10^{-6})}{d^{2}}

5,7=\frac{10998.10^{-3}}{d^{2}}

d^{2}= \frac{10998.10^{-3}}{57.10^{-1}}

d^{2}=192,94.10^{-2}

d= \sqrt[2]{192,94.10^{-2}}

d = 192,94.10^{ \frac{-2}{2} }

d =192,94.10^{-1}

d=1929,4m

OBS: Utilizei como K = 9.10^9
