A particle of charge \[-16\,\times {{10}^{-18}}C\] moving with velocity \[10\,m{{s}^{-1}}\] along the \[x\]-axis enters a region where a magnetic field of induction B is along the y-axis and an electric field of magnitude \[\text{1}{{\text{0}}^{\text{4}}}\text{V/m}\] is along the negative z-axis. If the charged particle continues moving along the \[x\]-axis, the magnitude of B is

A)  \[{{10}^{16}}\,Wb/{{m}^{2}}\]

B)  \[{{10}^{5}}\,Wb/{{m}^{2}}\]

C)  \[{{10}^{3}}\,Wb/{{m}^{2}}\]                    

D)         \[{{10}^{-3}}\,Wb/{{m}^{2}}\]
