4.4.98 - Electric potential in a radial field

Use V = Q/(4πε0r) for electric potential in a radial field.

Use - electric potential in a radial field to connect the rule to the data and decision in the question.

This matters because - electric potential in a radial field determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - electric potential in a radial field to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Electric potential in a radial field is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
