Quizplus · Accepted Answer

The direction of the electric field just outside a charged shell is perpendicular to the surface, pointing away from the shell if it's positively charged, or towards it if negatively charged. This is represented by the double arrow in option I ($\mathbf{C C}$), indicating a direction perpendicular to the surface at point $P_{2}$.
