3.50 nC of charge is consistently distributed in a solid Styrofoam ball of radius 2.00 cm cantered at x = 2.00 cm on the x-axis of a Cartesian coordinate system. -1.25 nC of charge is consistently distributed on a fibreglass spherical shell of radius 5.00 cm cantered on the source of the same coordinate system. What is the value of the electric flux by an imaginary spherical shell of radius 6.00 cm cantered on the source of the coordinate system in question?
