Flux coming out from a positive charge of \(8 \mathrm{C}\), placed in a medium of dielectric constant 4 is
- A \(\frac{1}{2 \varepsilon_0}\)
- B \(\frac{2}{\varepsilon_0}\)
- C \(8 \varepsilon_0\)
- D \(32 \varepsilon_0\)
Answer & Solution
Correct Answer
(B) \(\frac{2}{\varepsilon_0}\)
Step-by-step Solution
Detailed explanation
Charge enclosed, \(q=8 \mathrm{C}\) Electric flux, \(\phi=\frac{q}{\varepsilon_m}\) \[ \varepsilon_m=K \varepsilon_0 \] Dielectric constant, \(K=4\) \[ \phi=\frac{8}{4 \varepsilon_0} \Rightarrow \phi=\frac{2}{\varepsilon_0} \]
