1. The position vector of a particle moving in two dimensions, as a function of time 1, is given as F0)={it +jvr)e" for r>20. Starting at=0, the distance ofthe particle from the origin reaches its maximum value at = t, and at this instant, the velocity vector ỹ makes an angle a with f.The values of , and a are JNU 2014]J (a) and a= (c) and a = 0 (d) and a 2 (e) = l and a =
