A negative charge particle is moving upward in a magnetic field which is towards north. The particle is deflected towards

Step-by-step solution

The force on a moving charge in a magnetic field is given by the Lorentz force formula F = q( v B ) . Here, the charge q is negative. The velocity vector v is directed upward (along the positive z-axis, k ), and the magnetic field B is directed towards the north (along the positive y-axis, j ). The cross product v B is k j = - i , which points towards the west. Since the charge q is negative, the force F = q( v B ) will be in the direction opposite to v B . Therefore, the force is directed towards the east. Answer:
