An electron enters the space between the plates of a charged capacity as shown. The charge density on the plate is `sigma`. 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 `vec(E)` and `vec(B)` without any change in direction
The time taken by the electron to travel a distance l in that space is

Options

A. `(sigma B)/(epsilon_0l)`
B. `(sigma l)/(epsilon_0 B)`
C. `(epsilon_0l)/(sigma B)`
D. `(epsilon_0lB)/sigma`

Answer

D
