this question is quite easy. we know that {\mathbf  {F}}=q{\mathbf  {E}}+q{\mathbf  {v}}\times {\mathbf  {B}}
of course E=0 in the question, so the direction of force is perpendicular to the plane contained by and B. for eg, in second part of ques, force will be directed into the plane.
you can use the above method for all parts of the ques
