An electron enters a magnetic field of 0.75 T with a velocity perpendicular to the direction of the field. At what frequency does the electron traverse a circular path? (mel = 9.11  10-31 kg, e = 1.60  10-19 C)
 
  A) 2.1  1010 Hz
  B) 4.8  10-7 Hz
  C) 2.1  1014 Hz
  D) 4.8  10-11 Hz

Question 2

How does the equilibrium rule, F = 0, relate to Newton's first law of motion?
 
  What will be an ideal response?

Answer to Question 1

A

Answer to Question 2

Answer: The equilibrium rule states Newton's first law of motion in equation form So it relates very well. When no net force acts on an object, the motion of the object doesn't change. If at rest it remains at rest. If moving with constant velocity, it remains moving at constant velocity.
