This is a Multiple Choice Questions as classified in NCERT Exemplar
Answer – (a, c)
Explanation- Gauss's law states that the total electric flux of an enclosed surface is given by q/? 0, where q is the charge enclosed by the surface.
So total charge inside the surface is = Q-2Q = -Q
Therefore total flux through the surface of the sphere = -Q/? 0
Now, charge 5Q is lies outside the surface, thus it makes no contribution to electric flux through the given surface. So both option a and c are true.

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.
