QJEEM22Ph9509: JEE Main 2022 Physics - Class 12 JEEM22Ph9509 Solution: A uniform electric field E = ( 8   m / e ) V / m is…

A uniform electric field E=(8 m/e)V/m 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. The angle of the deviation (θ) of the path of the electron as it comes out of the field will be _________.

Multiple Choice Options

  • A tan−1⁡(4)
  • B tan−1⁡(2)
  • C tan−1⁡(13)
  • D tan−1⁡(3)

Step-by-Step Verified Solution

E=8me V/m

l=1 m

vx=2 m/s

ay=−8 m/s2

t=lvx=12s

⇒|vy|=4 m/s

⇒ angle of deviation = θ

tan⁡θ=vyvx

θ=tan−1(42)=tan−1(2)
