A particle of charge –16 × 10–18 coulomb moving with velocity 10 ms–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 104 V/ m is along the negative z–axis. If the charged particle continues moving along the x–axis, the magnitude of B is
10–3 Wb/m2
103 Wb/m2
105 Wb/m2
1016 Wb/m2
