A uniform electric field E is created between two parallel
., charged plates as shown in figure . An electron
. enters the field symmetrically between the plataes with a
. speed `v_0. The length of each plate is l. Find the angle of
. deviation of the path of the electron as it comes out
. of the field.
θ = tan − 1 E l m v 2 0 θ = tan − 1 ( e E l m v 2 0 ) θ = tan − 1 ( e E l m v 0 ) θ = tan − 1 ( e E m v 2 0 )

Options

A. `theta="tan"^(-1) (El)/(mv_(0)^(2))`
B. `theta="tan"^(-1) ((e El)/(mv_(0)^(2)))`
C. `theta=tan^(-1) ((e El)/(mv_(0)))`
D. `theta=tan^(-1) ((e E)/(mv_(0)^(2)))`

Answer

B
