Consider a region inside which there are various types of charges but the total charge is zero ,.At points outside the region

A uniform but time varying magnetic field exists in cylindrical region and directed into the paper. If field decreases with time and a positive charge is placed at any point inside the region, then it moves :-

A point charge +Q is surrounded by two uncharged concentric conducting shells as shown. The region of space inside the inner shell is A, the region of space between the two shells is B and the regionof space outside of the outer shell is C. Regarding the electric field whihc of the following is correct?

If the charge distribution within Gaussian surface is changed, but total charge inside it remains unchanged, will there be any change in the electric field strength outside inside the Gaussian surface?
