Answer:
east direction.
Explanation:
Given, that the electron is travelling in the north direction in the horizontal direction whereas the magnetic field applied is in the vertically downward direction.
Using the Maxwell's left hand rule, we point the index finger in the direction of magnetic field while the perpendicular middle finger points in the direction of motion of the positive charge and the thumb points in the direction of the force. During this position the angle between all the three fingers must be mutually perpendicular to each other.
Therefore we find that here in this case the magnetic force on the electron acts in the east direction.
The first finger points in the direction of the magnetic field and the middle finger in the direction of the electric current. In the east direction the magnetic force act on the electron.
The thumb will point in the direction of the force on the conductor if the thumb and first two fingers of the left hand are arranged at right angles to each other on a conductor and the hand is oriented.
So that the first finger points in the direction of the magnetic field and the middle finger in the direction of the electric current.
Given that the electron travels in a horizontal north-south path, whereas the magnetic field applied is vertically downward.
We point the index finger in the direction of the magnetic field, the perpendicular middle finger in the direction of positive charge motion, and the thumb in the direction of force using Maxwell's left-hand rule.
Hence in the east direction the magnetic force act on the electron.
