A cylinder of radius \(r\) and length \(l\) is placed in an uniform electric field \(E\) parallel to the axis of the cylinder. The total flux for the surface of the cylinder is given by
- A \(\pi r^{2} E\)
- B \(\left(\pi r^{2}+\tau l^{2}\right) E\)
- C Zero
- D \(2 \pi r^{2} E\)
Answer & Solution
Correct Answer
(C) Zero
Step-by-step Solution
Detailed explanation
The given diagram represents a cylinder placed in a uniform electric field. Let \(\phi_{1}\) and \(\phi_{2}\) be the flux coming out of a circular cross-sectional surface. \(\phi_{3}\) is flux through the curved surface. Since, normal to a curved surface is always \(90^{\circ}\)…
