The charge density on the plate is σ . Electric intensity in the space between the plates is E. A uniform magnetic field B also exists in that space perpendicular to the direction of E. The electron moves perpendicular to both E→ and B→ without any change in direction. The time taken by the electron to travel a distance l in that space is
