Exam-style question
Try this first
A mass of 10 kg is placed in a gravitational field where the gravitational force acting on it is 50 N. Calculate the gravitational field strength. Scenario focus: orbital motion in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
Model answer
What a good answer should say
- The gravitational field strength is 5 N/kg.
Explanation
Why this works
The correct answer is The gravitational field strength is 5 N/kg.. This is correct for Gravitational fields because the stem is testing orbital motion; the chosen option keeps the field quantity, source interaction, direction, and unit consistent.
The alternatives are weaker because they mix gravitational, electric, magnetic, orbital, or transformer ideas, or they attach the right number to the wrong physical meaning.
