A particle initially moving towards south in a vertically downward magnetic field is deflected toward the east. What is the sign of the charge on the particle?

Assertion : A beam of protons is moving towards east in vertically upward magnetic field. Then, this beam will deflect towards south. Reason : A constant magnetic force will act on the proton beam.
