A particle A starts from the point P whose position vector is aî +3ĵ+2ĸ with constant velocity vector î+ĵ+ĸ. Simultaneously a second perticle B leaves the point Q whose position vector is 7î -2ĵ+4ĸ. Find the velocity vector of A relative to B and the position vector of A relative to B at this time. If the distance AB is least when t=2, find the value of a.
