Answer: 168.75 N
Explanation:
first, let's convert microcoulombs to coulombs
q1 = 1e-4 C
q2 = 3e-5 C
r = 0.4 m
then use the equation Fe =
plug in values --> F = (9e9*1e-4*3e-5)/(0.4)^2
F = 168.75 N
Answer:
B. The initial velocity has components both parallel and perpendicular to the magnetic field
Explanation:
A moving charged particle can be deflected by a magnetic field, only when some component of its velocity is perpendicular to the direction of the magnetic field.
A particle will move in a circular path when it has only one velocity component and it is perpendicular to the magnetic field. <em>If</em> the particle has a component that is parallel to the magnetic field, its magnitude and direction is not altered since ; The result is a circular orbit in the plane perpendicular to the magnetic field, and straight line motion parallel to the magnetic field—a helical path.
