SUMMARY
The electric field in spherical shells is determined by the net charge present on the conductor. When the net charge is -Q, the electric field at points outside the shell (r > b) is zero, as confirmed by the discussion referencing the video at 3:00-3:10. The relationship between electric flux and electric field is governed by the equation Flux = E*A = q/ε₀, where ε₀ is the permittivity of free space. This principle applies regardless of whether the charge is -Q or -3Q.
