A large number of positive charges each of magnitude \(q\) are placed along the \(X\)-axis at the origin and at every \(1 \mathrm{~cm}\) distance in both the directions. The electric flux through a spherical surface of radius \(2.5 \mathrm{~cm}\) centred at the origin is
- A \(\frac{5 q}{\varepsilon_0}\)
- B \(\frac{8 q}{\varepsilon_0}\)
- C \(0\)
- D \(\infty\)
Answer & Solution
Correct Answer
(A) \(\frac{5 q}{\varepsilon_0}\)
Step-by-step Solution
Detailed explanation
The given situation is shown below From the above figure total charge enclosed by the sphere of radius \(2.5 \mathrm{~cm}=5 q\) \(\therefore\) According to gauss law, total electric flux passing through spherical surface,…
