φE=(q/K ϵ 0)=(0.5/10 × 8.85 × 10- 12)=5.65× 109SIunit

Q. The total flux (in S.I. units) through a closed surface constructed around a positive charge of $0.5 C$ placed in a dielectric medium of dielectric constant $10$ is

$5.65 \times 1 0^{9}$

$1.13 \times 1 0^{11}$

$9 \times 1 0^{9}$

$8.85 \times 1 0^{- 12}$

$ϕ_{E} = \frac{q}{K ϵ _{0}} = \frac{0.5}{10 \times 8.85 \times 1 0 ^{- 12}} = 5.65 \times 1 0^{9} S I u ni t$
