if uncertainly in position and velocity are equal then uncertainty in momentum will be......?
Heisenberg uncertainity principle states that , " It is not possible to determine precisely both the position and the momentum (or velocity) of a small moving particle.
Mathematically,
          if are the uncertainities in the position and momentum respectively
then,
  m - mass,
(i) If 100% uncertainity in its velocity is assumed then and
(ii) If 100% uncertainity in its position is assumed then
     
Hence,
 unceertainity principle shows that the simultaneous measurement of position and momentum of a particle with absolute zero is not possible.


Thus uncertainity in position of the particle will be infinite.
