Questions
A 10 eV electron is circulating in a plane at right angles to a uniform field of magnetic induction 10-4 Wb/m2 (= 1.0 gauss), the orbital radius of electron is
detailed solution
Correct option is C
K.E. of electrons =10eV∴ 12mv2=10×1.6×10−19or V=1⋅875×106m/s and Bev=mv2ror r=mveB=11×10−2m=11cmTalk to our academic expert!
