Two particles A and B start from origin ...

Two particles A and B start from origin of a coordinate system towards point P(10,20) and Q (20,10) respectively with speed `5sqrt(5)` each. Both continue their motion for 10 s and then stop. There after particle B moves towards particle A with speed `2sqrt(2)` and after particle B meets particle A, they both return to origin following a straight line path with speed `5sqrt(5)`. Match the items of column-I with suitable item of Column-II.
