An electromagnetic wave with a peak magnetic field component of 7.3 × 10−⁷ T has an associated peak electric field component of what value? (μ₀ = 4π × 10−⁷ T⋅m/A,ε₀ = 8.85 × 10−¹² C²/N⋅m²,and c = 3.00 × 10⁸ m/s) A) 45 N/C B) 2.0 × 10−⁵ N/C C) 2.2 × 10² N/C D) 0.50 × 10−¹⁵ N/C

Question

Quizplus · Accepted Answer

The peak electric field (E) is related to the peak magnetic field (B) by the equation E = cB, where c is the speed of light. Substituting the given values, E = (3.00 × 10^8 m/s)(7.3 × 10^−7 T) = 2.19 × 10^2 N/C, which is approximately 2.2 × 10^2 N/C.
