Exam-style question
Try this first
A mass of 10 kg is placed in a gravitational field with a gravitational field strength of 9.81 N/kg. Calculate the weight of the mass. Scenario focus: electric fields 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 weight of the mass is 98.1 N.
Explanation
Why this works
The correct answer is The weight of the mass is 98.1 N.. This is correct for Gravitational fields because the stem is testing electric fields; 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.
