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 = $\frac{21.2\times10^{-9}}{8.85\times10^{-12}}$

2.4 x 10³ Nm²/C
