Options
- AE_y=10.5 (1.5 10^3 x+0.5 10¹¹ t ) Vm ⁻¹
- BE_z=1.17 (1.5 10^3 x+0.5 10¹¹ t ) Vm ⁻¹
- CE_y=1.17 (1.5 10^3 x+0.5 10¹¹ t ) Vm ⁻¹
- DE_z=105 (1.5 10^3 x+0.5 10¹¹ t ) Vm ⁻¹
Correct answer
D. E_z=105 (1.5 10^3 x+0.5 10¹¹ t ) Vm ⁻¹
Step-by-step solution
aligned & E ₀= B ₀ C & E ₀=3 10^8 (3.5 10⁻⁷ ) (1.5 10^3 x +0.5 10¹¹ t ) & E ₀=105 (1.5 10^3 x +0.5 10¹¹ t ) Vm ⁻¹ aligned Data inconsistent while calculating speed of wave. You can challenge for data.
