Q9. A uniform electric field E = ( 8me )V m−1 is created between two parallel plates of length 1 m as shown in figure, (where m = mass of electron and e = charge of electron). An electron enters the field symmetrically between the plates with a speed of 2 m s−1 . The angle of the deviation (θ) of the path of the electron as it comes out of the field will be _____ . (1) tan−1(4) (2) tan−1(2) (3) tan−1( 13 ) (4) tan−1(3)
What This Question Tests
