Question
Refer to the diagram below. Several charged particles move with the velocities shown it feels due to the carries a current. I. Label each particle with the direction of the force that to the current in the wire or write "F=0" if there is no force. Refer to the diagram below. Several charged particles move with the velocities shown near a wire that carries a current, I. (It is an end view of the wire.) Label each particle with the direction of the force that it feels due to the current in the wire or write "F=0" if there is no force.Explanation / Answer
Part a)
The right-hand rule determines that the magnetic field is in concentric circles cable, the thumb points the direction of the current and fingers the field direction
the magnetic force is given by the two expressions
F = q v x B
F = I L x B bold letters indicate vectors
analyze each
positive charge, entering the page
v and B are parallel this implies Without 0 = 0 F = 0
positive charge moving to the right
v and B are perpendicular F = qvB
with direction to the wire carrying current
negative charge, steering angle
v and b have a perperdicular component to Vx field in this case this speed is affected by the field and has a force that is directed to the wire being alleged.
The other component does not change
Part b)
Live wire coming out of the page, concentric magnetic field in the plane of the page
Speed negative charge to the right
V and B perpendicular
F in the direction of entering the page, with the right-hand rule
speed up positive charge
V and B perpendicular
F direction out page
V positive charge out page
V and B perpendicular
F to the line that carries current
