An electron enters the space between the plates of a charged capacitor as shown. The charge density on the plate is σ Electric intensity in the space between the plates is E .A uniform magnetic field also exists in the 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 I in the space is
