Answer:

Explanation:

1st-The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). ... The force on an individual charge moving at the drift velocity vd is given by F = qvdB sin θ.

2nd - Since the positively charged particle is projected towards west, so the direction of current is towards west. Now the deflection is towards north, so the force is towards north.
