Question

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

• A. $5.65\times 10^{9}$
• B. $1.13\times 10^{11}$
• C. $9\times 10^{9}$
• D. $8.85\times 10^{- 12}$

Answer 1

Answer: (A)

$\phi_{E}=\frac{q}{K \epsilon _{0}}=\frac{0.5}{10 \times 8.85 \times 10^{- 12}}=5.65\times 10^{9}SIunit$
