A potential difference of 600 V is applied across the plates of a parallel plate condenser. The separation between the plates is 3 mm. An electron projected vertically, parallel to the plates, with a velocity of `2xx10^(6)m//s` moves undeflected between the plates. Find the magnitude of the magnetic field (in T) in the region between the condenser plates. (Neglect the edge effects) `square` .
(Charge of the electron `=1.6xx10^(-19)C`)

Options

A. `0Wb//m^(2)`
B. `2.5Wb//m^(2)`
C. `3.0Wb//m^(2)`
D. `5.0Wb//m^(2)`

Answer

B
