Question

Electron accelerated by a potential of 250 V enter the electric field at an angle of incidence 45o and get reflected through an angle of 30o. Find the potential difference between two regions

Answer 1

Answer:

T=eV=21mv2

υ=m2eV

⟹υH=m2eVcosα and υv=m2eVsinα 

Now, rmυv2=Beυv or r=Bemυv

and T=υv2πr=Be2πm

Pitch P=υHT=Be2πmm2eVcosα=0.02m
