Question
A material with susceptibility chi = 5 × 10⁻³has a relative permeability μ_r of:
Explanation
Given:
A material with susceptibility chi = 5 × 10⁻³has a relative permeability μ_r of:
Formula:
μ_r = 1 + chi.
Substitution & Calculation:
Given: chi = 5 × 10⁻³. Substitute: μ_r = 1 + 5 × 10⁻³= 1.005 .
Final Result:
The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
