Question

An electron is moving along + x direction with a velocity of 6 × 10 6 ms - 1 . It enters a region of uniform electric field of 300 V / c m 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:
