An electron (mass = 9x10-31 kg, charge = 1.6 x 10-19 C) moving with a velocity of 106 m/s enters a region where magnetic field exists. If it
describes a circle of radius 0.10m, the intensity of the magnetic field must be
detailed solution
Correct option is B
r=mvqB∴ 0⋅10=9×10−311061⋅6×10−19Bor B=9×10−311061.6×10−19(0⋅10)=5⋅6×10−5 teslaTalk to our academic expert!
