Question

Electrons are accelerated from rest through apotentialdifference of V_o and then passthrough aregion between two parallel metal plates. The regionbetweenplates contains a uniform electric field E and uniformmagneticfield B. With only electric field present electronsfollowpath 1. With only magnetic field present electrons followpath3 . With both fields present electrons pass undeflectedalongstraight path 2

a) Describe shape of the portion of path 1 betweenplates

Justify your answer

b) what is direction of electric field Explain

c) Describe shape of portion of path 3 between plates. Justifyyour answer

d) Between plates the magnitude of electric field is 3.4 x10⁴ V/m and magnitude of magnetic field is 2.0 x10^-3 T Claculate speedofelectrons given they are undeflected when both fieldsarepresent

e) Calculate V _o , potential difference,required toaccelerate electrons to speed determined above
