To draw the missing vector, it is necessary to know the relation between the direction of the three vectors v, B and F.
It is given by the right hand rule, which states that to find
the direction of the magnetic force on a positive moving charge,
the thumb of the right hand point in the direction of v, the
fingers in the direction B then the force F is directed
perpendicular to the right hand palm. For a negative charge, F will
be opposite, that is pointing towards the back of the palm.
Here the charge is negative.
Thus, we have the following:

Force on Moving Charges in a Magnetic Field
Magnets exert forces on other magnets even though they are separated by some distance. Usually the force on a magnet (or piece of magnetized matter) is pictured asthe interaction of that magnet with the magnetic field at its location (the field being generated by other magnets or currents). More fundamentally, theforce arises from the interaction of individual moving charges within a magnet with the local magnetic field. This force is written ,where is the force, is the individual charge (which...
