As per your syllabus, 1 joule equals which combination of SI base units?

1 kg s
1 kg m² s⁻² (since 1 N = 1 kg m s⁻², and J = N × m)
1 kg m s⁻¹
1 kg m²

Show answer and solution

Correct answer: B. 1 kg m² s⁻² (since 1 N = 1 kg m s⁻², and J = N × m)

As per your syllabus, 1 J = 1 N × 1 m = (1 kg m s⁻²) × m = 1 kg m² s⁻². The other options miss factors.
