How does the gravitational force change if the distance between two masses 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.The gravitational force is halved.
- B.The gravitational force is doubled.
- C.The gravitational force is quadrupled.
- D.The gravitational force remains the same.
Model answer
What a good answer should say
- The gravitational force is halved.
Explanation
Why this works
The correct answer is The gravitational force is halved.. 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.
