What is the gravitational field strength at a distance of 3 meters from a mass of 12 kg? 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.0.13 N/kg
- B.0.44 N/kg
- C.1.33 N/kg
- D.4.00 N/kg
Model answer
What a good answer should say
- 0.44 N/kg
Explanation
Why this works
The correct answer is 0.44 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.
