An electron is moving along +x direction with a velocity of 6 $ \times $ 106 ms–1. It enters a region of uniform electric field of 300 V/cm pointing along +y direction. The magnitude and direction of the magnetic field set up in this region such that the electron keeps moving along the x direction will be :

Question

An electron is moving along +x direction with a velocity of 6 $ \times $ 10⁶ ms^–1. It enters a region of uniform electric field of 300 V/cm pointing along +y direction. The magnitude and direction of the magnetic field set up in this region such that the electron keeps moving along the x direction will be :

3 $ \times $ 10^–4 T, along –z direction

5 $ \times $ 10^–3 T, along –z direction

5 $ \times $ 10^–3 T, along +z direction

3 $ \times $ 10^–4 T, along +z direction
