A particle of charge

16 \times 10^{-16}

C moving with velocity

10 \text{ ms}^{-1}

along

x

-axis enters a region where magnetic field of induction

\vec{B}

is along the

y

-axis and an electric field of magnitude

10^4 \text{ Vm}^{-1}

is along the negative

z

-axis. If the charged particle continues moving along

x

-axis, the magnitude of

\vec{B}

is : (1)

16 \times 10^3 \text{ Wb m}^{-2}

(2)

2 \times 10^3 \text{ Wb m}^{-2}

(3)

1 \times 10^3 \text{ Wb m}^{-2}

(4)

4 \times 10^3 \text{ Wb m}^{-2}
