ANSWER:
Solution 83PE
a.) The direction of the magnetic force can be determined by the right hand rule-1.
According to this rule for a positive moving charge, right thumb is in the direction of velocity, fingers point in the direction of magnetic field and palm points in the direction of magnetic force.
