Expert Answer
According to gauss theorem we know that the electric flux through a closed surface enclosing a charge is equal to 1/ε0 times the magnitude of the charge enclosed.
The charge enclosed by the sphere = +3Q
Therefore in this case the electric flux emanating out of the sphere of radius 3a with its centre at the origin,
