Consider a charged particle of mass m = 0.002 kg and charge q = -7 μC.
The particle is moving to the right (in the plane of the page) at velocity v = 108 m/s in a region of space that has uniform electric and magnetic fields. The electric and magnetic forces are the only forces acting on the particle, and the particle moves in
a straight line with constant speed.
The electric field points down on the page (as shown), with magnitude E = 168 N/C
a) If the magnetic field does not have any component parallel to the velocity, then what is the magnitude of the magnetic field?
b) What is the direction of the magnetic field?
O Towards the top of the page
Into the page
Out of the page
O To the right on the page
Towards the bottom of the page
To the left on the page
O Can't be determined from the information provided

c) Consider what will happen if the electric field is suddenly turned off while keeping the magnetic field unchanged. The motion of the charged particle after the electric field is turned off can be described as a
O A counterclockwise circle in the plane of the page (as viewed from your perspective looking at the drawing)
A spiral of decreasing pitch
O A straight line with decreasing speed
A spiral of increasing pitch
O A straight line with increasing speed
A clockwise circle in the plane of the page (as viewed for your perspective looking at the drawing)
O A circle, with the plane of the circle perpendicular to the page
Transcribed Image Text:Consider the same charged particle moving in a uniform magnetic field with velocity and magnetic field vectors as shown below.
v = 108 m/s and
B = 0.530 Tesla
0= 56 degrees.
Note: There is no electric field for this part of the question.
