At a particular point in space and time, E→=6.3j^ V/m.\overrightarrow E = 6.3\widehat j\,V/m.E=6.3jV/m. The corresponding magnetic field B,→\overrightarrow {B,}B, at that point will be :A18.9 ×\times× 10^−-−8 k^\widehat kkTB2.1 ×\times× 10^−-−8 k^\widehat kkTC6.3 ×\times× 10^−-−8 k^\widehat kkTD18.9 ×\times× 10⁸ k^\widehat kkTCheck answerSkip
