Choose the incorrect statement : \((a)\) The electric lines of force entering into a Gaussian surface provide negative flux. \((b)\) A charge ' \(q\) ' is placed at the centre of a cube. The flux through all the faces will be the same. \((c)\) In a uniform electric field net flux through a closed Gaussian surface containing no net charge, is zero. \((d)\) When electric field is parallel to a Gaussian surface, it provides a finite non-zero flux. Choose the most appropriate answer from the options given below

Answer & Solution

Correct Answer

(C) \((d)\) only

Step-by-step Solution

Detailed explanation

Since \(\phi=\vec{E} \cdot \vec{A}=E A \cos \theta\)

\(\theta=90^{\circ}\)

\(\therefore \phi=0\)
