According to Right-hand rule, the direction of force (F) on positively charged particle will be perpendicular to the plane of paper upward and on negatively charged particle will be perpendicular to the plane of paper downwards.
As, F=q(v*B) or F=q(v*B)=qvB sin0 if v=1,q=1 and sin 0=1 or 0=90degree, then f= 1*1*B*1 = B
