Five charges q1, q2, q3, q4 and q5 are fixed at their positions as shown in figure, S is a Gaussian surface. The Gauss’ law is given by
Which of the following statements is correct? (a) E on the LHS of the above equation will have a contribution from q1 ,q5 and q1, q5 and q3 while q on the RHS will have a contribution from q1 and q4 only
(b) E on the LHS of the above equation will have a contribution from all charges while q on the RHS will have a contribution from q2 and q4 only (c) E on the LHS of the above equation will have a contribution from all ch arges while q on the RHS will have a contribution from q1, q3 and q5 only (d) Both E on the LHS and q on the RHS will have contributions from q2 and q4 only

Answer. (b)
Explanation-The charges may be located anywhere inside the surface, if the surface is so chosen that there are some charges inside and some outside, the electric field on the left side of equation is due to all charges, both inside and outside S.

The following are the topics covered in this chapter: Electric Field and Field Lines, Gauss's Law, Electric Dipole, Conductors and Insulators, and Electric Flux.
Indeed, it is an easy chapter of Class 12 Physics. In this chapter, you will learn about the foundational concepts like Gauss's law and electric fields.
In the medical entrance test NEET, this chapter has a moderate weightage. You can expect around 2-3 questions of this chapter that contributes to the 3-5% of the total marks in the Physics section.
