4.4.93 - Electric field strength

Understand electric field strength E = F/Q and use this relationship.

Use - electric field strength to connect the rule to the data and decision in the question.

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

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

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