The electric field outside a spherically symmetric charged object is described as:

1. Symmetry constrains the direction the field can point. 2. Consider the field outside a spherically symmetric charged object. 3. That electric field is radial. 4. Its magnitude varies with the radial distance from the centre of the object. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 18 'Electric Charge and Electric Field', sections 18.1-18.8_
