HERE IS YOUR ANSWER
a). by Fleming's left hand rule
the forefinger , the central finger and the thumb of the left hand are stretched in such a way that they are mutually perpendicular to each other . if the central finger shows the direction of velocity of positive charge and forefinger shows the direction of the magnetic field , then the thumb will give the direction of magnetic force . if instead of positive charge we have negative charge , then the direction of magnetic force is in opposite direction
therefore
if a positive charge then the direction of magnetic force will be north or upside
if a negative charge then the direction of magnetic force will be south or downside
b) the force of magnetic force is given by
BqV sin theata
B is the magnetic field
q is the charge
V is the velocity
theata is the angle between V and B
HOPE MY ANSWER IS CORRECT
