  1. Question 1

    Q1. A crystal has a dielectric constant of 10. What is the polarization if the electric field is 10⁴ V/m?

    • A) 8.85 * 10^(-7) C/m²
    • B) 7.96 * 10^(-7) C/m²
    • C) 8 * 10^(-7) C/m²
    • D) 9 * 10^(-7) C/m²

    Answer: 8.85 * 10^(-7) C/m²

    Explanation: Using P = ε₀(ε_r - 1)E, we get P = 8.85 * 10^(-12) * (10 - 1) * 10⁴ = 8.85 * 10^(-7) C/m².
