Magnetics question

2025 · 4 Apr · Shift 2 · Q73

JEE MainPhysicsMagneticsNumerical+4 / −1
If an optical medium possesses a relative permeability of 10π\frac{10}{\pi}π10​ and relative permittivity of 10.0885\frac{1}{0.0885}0.08851​, then the velocity of light is greater in vacuum than that in this medium by ‾\underline{\hspace{2cm}}​ times. (μ0=4π×10−7H/m,ϵ0=8.85×10−12 F/m,c=3×108 m/s)\left(\mu_0=4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}, \epsilon_0=8.85 \times 10^{-12} \mathrm{~F} / \mathrm{m}, \mathrm{c}=3 \times 10^8 \mathrm{~m} / \mathrm{s}\right)(μ0​=4π×10−7H/m,ϵ0​=8.85×10−12 F/m,c=3×108 m/s)
