Answer: (1/L)√(F/μ).
- A L√(F/μ)
- B (1/L)√(μ/F)
- C (1/L)√(F/μ)
- D (1/L²)√(F/μ)
Correct answer: C. (1/L)√(F/μ)
Explanation: Matching dimensions, f = (1/2L)√(F/μ), so f ∝ (1/L)√(F/μ).
The 7 SI base units. All derived units (newton, joule, watt, volt, etc.) can be expressed as combinations of these 7 fundamental units raised to various powers.
