Answer:
306500 N/C
Explanation:
The magnitude of an electric field around a single charge is calculated with this equation:
[tex]E(r) = \frac{1}{4 \pi *\epsilon 0} \frac{q}{r^2}[/tex]
With ε0 = 8.85*10^-12 C^2/(N*m^2)
Then:
[tex]E(0.89) = \frac{1}{4 \pi *8.85*10^-12} \frac{27*10^-6}{0.89^2}[/tex]
E(0.89) = 306500 N/C
