The electric flux from a cube of edge \(l\) is \(\phi\) in an enclosed charge. If the edge of the cube is made \(\frac{2}{3} l\) and the charge enclosed in the cube is doubled, then the electric flux value will be
- A \(4 \phi\)
- B \(2 \phi\)
- C \(\frac{\phi}{2}\)
- D \(\phi\)
Answer & Solution
Correct Answer
(B) \(2 \phi\)
Step-by-step Solution
Detailed explanation
According to Gauss's law, the electric flux through a closed surface is Electric flux, \(\phi=\frac{Q}{\varepsilon_0}\) ...(i) Electric flux through a closed surface does not depend on the dimensions of closed surface, it depends only the amount of charge enclosed by the closed…
