The magnetic field of an electromagnetic wave is given by:
B=1.6×10⁻⁶cos(2×10⁷z+6×10¹⁵t)(2i+j) Wbm²
The associated electric field will be:
A. E=4.8×10²cos(2×10⁷z+6×10¹⁵t)(i−2j) V/m
B. E=4.8×10²cos(2×10⁷z+6×10¹⁵t)(−i+2j) V/m
C. E=4.8×10²cos(2×10⁷z−6×10¹⁵t)(2i+j) V/m
D. E=4.8×10²cos(2×10⁷z−6×10¹⁵t)(−2j+i) V/m
