Exam-style question
Try this first
How does the gravitational force between two objects change if the distance between them is doubled? Scenario focus: orbital motion in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
- A.It doubles.
- B.It quadruples.
- C.It halves.
- D.It becomes one-fourth.
Model answer
What a good answer should say
- It becomes one-fourth.
Explanation
Why this works
The correct answer is It becomes one-fourth.. 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.
