Question

For the cylinder in the piecewise-uniform field, the charge enclosed is:

विकल्प

• 5.56 × 10⁻¹¹ C

• 1.39 × 10⁻¹¹ C

• 2.78 × 10⁻¹¹ C

• 1.05 × 10⁻¹¹ C

Answer 1

Using Gauss's Law with net flux \[\Phi ≈ 3.14 \text{ N m}^2\text{C}^{-1}\], the enclosed charge is \[q_{enclosed} = \varepsilon_0 \Phi = 8.85 × 10^{-12} × 3.14 \approx 2.78 × 10^{-11} \text{ C}\].
