The charged concentric conducting spherical shells.
Solution Preview
In general you have an idea in the correct direction. I shall correct small errors.
From your writing I deduce that you use the SI system of units
The total flux through a sphere of radius R is
4 pi R^2 E = SumOfAllQsInside / e_0,
where e_0 = 8.854E-12 C²/Nm²
(A) for 0 < r < a you only have q inside the sphere, so
E = q / (4 pi e_0 r^2)
(B) for a < ...
