An electron is projected vertically upward with a speed of 1.10×106m/s into a uniform magnetic field of 0.440 T that is directed horizontally away from the observer What is the radius of the motion?.
magnetic force acting on the electron,
F = q*v*B*sin(90)
m*a_rad = q*v*B
m*v^2/r = q*v*B
==> r = m*v/(B*q)
= 9.11*10^-31*1.1*10^6/(0.44*1.6*10^-19)
= 1.42*10^-5 m

An electron is projected vertically upward with a speed of 1.50×106 m/s into a uniform magnetic field of 0.590 T that is directed horizontally away from the observer. Part A Describe the electron's path in this field. Describe the electron's path in this field. The electron will move in a straight line with acceleration. The electron will move in a clockwise circular path if viewed in the direction of the magnetic field. The electron will move in a straight line...
An electron is projected with an intial speed of 1.60x10^6 m/s into the uniform field between the parallel plates in the figure. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates.A. If the electron just misses the upper plate as it emerges from the field, find the speed of the electron as it emerges from...
#2 near the ground at the north magnetic pole, the earth’s magnetic field is directed downward vertically and has a strength of 0.57 G. An electron at the north pole is projected from the ground into this magnetic field with a velocity of 1.4 km/s vertically upward and 1.9 km/s horizontally to your right.
