Answer:
Explanation:
According to Gausses theorem, electric flux coming out of charge on all sides q is equal to
q / ε₀
q is charge , ε₀ is permittivity of air whose value is given by
8.85 x 10⁻¹²; q = 21.2 x 10⁻⁹ C
Putting the values we get
FLUX = [tex]\frac{21.2\times10^{-9}}{8.85\times10^{-12}}[/tex]
2.4 x 10³ Nm²/C
