Two particles A and B moving in x-y plane are at origin at t=0 sec. The initial velocity vectors of A and B are ${\overrightarrow{u}}_A=8\widehat{i}m/s$ and ${\overrightarrow{u}}_B=8\widehat{j}m/s.$ The acceleration of A and B are constant and are ${\overrightarrow{a}}_A=-2\widehat{i}m/s^2$ and ${\overrightarrow{a}}_B=-2\widehat{j}m/s^2.$ Column-I gives certain statements regarding particle A and B. Column-II gives corresponding results. Match the statements in Column-I with corresponding results in Column-II.
