State whether the following statements are True (T) or False (F): The magnitude of electric field intensity at a point near a infinite plane sheet of uniform charge density varies inversely as the distance of the point of obervation form the source charge.

Electric potential at a point due to a point charge varies……….as the distance between the point of observation and the point charge.

Electric field intensity at an outside point of a charged thin spherical shell is
