A particle of charge `-16 times 10^(-19) C` moving with velocity `10 mg^(-1)` along the `x` -axis ẹnters a region where magnetic field `B` is along the `y` axis and electric field of magnitude `10^(4)` (V/m) is along the negalive z-axis If the charged particle contintes moving along the `x` -axis, then the magnitude of `B((Wb) / (m)^(2))` is
