Calculate the gravitational potential energy of a 5 kg mass at a height of 10 m in a gravitational field strength of 9.81 N/kg. 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 gravitational potential energy is 490.5 J.
Explanation
Why this works
The correct answer is The gravitational potential energy is 490.5 J.. 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.
