Final answer:
The field just outside a 3.50 cm radius is an Electric field. The electric field outside a spherically symmetric charged object is radial, extending outwards from the center of the object.
Step-by-step explanation:
The field just outside a 3.50 cm radius is an Electric field.
According to Essential Knowledge 2.C.3, the electric field outside a spherically symmetric charged object is radial, meaning it extends outwards in all directions from the center of the object. Its magnitude varies as the inverse square of the radial distance from the center.
