1. The problem statement, all variables and given/known data

This is the question.
Charges q1= -6Q and q2 = +2Q are located at x =-a and x = +a, respectively.

2. Relevant equations
Part A
What is the net electric flux through a sphere of radius 2a centered at the origin?
Part B
What is the net electric flux through a sphere of radius 2a centered at x=2a?

NEED help with part B

3. The attempt at a solution

For part A
i did $$\Phi$$ = (-6Q+2Q)/E ; so = -4Q/E

Draw a 2D sketch of the sphere in part B....which charge(s) does it enclose?
