An electron moving with a speed along the positive x-axis at y = 0 enters a region of uniform magnetic field `vecB= Bohatk` which exists to the right of y - axis. The electron exits from the region after some time with the speed at co-ordinate y then.
An electron moving with a speed u along the positive x-axis
Options:
(a) `ν > v_o , y < 0` (b) `ν = v_o , y > 0` (c) `ν > v_o , y > 0` (d) `ν = v_o , y < 0`
