Calculate the orbital speed of a satellite orbiting a planet with a mass of 5.97 x 10^24 kg at an orbital radius of 7.0 x 10^6 m. Use G = 6.67 x 10^-11 N m²/kg². Scenario focus: transformers 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
- Orbital speed = 3,769 m/s.
Explanation
Why this works
The correct answer is Orbital speed = 3,769 m/s.. This is correct for Gravitational fields because the stem is testing transformers; 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.
