If uncertainty in position and momentum are equal, then uncertainty in velocity is

Step-by-step solution

Key Idea: According to Heisenberg's uncertainty principle, it is impossible to determine simultaneously the position and momentum of a moving microscopic particle, ie, aligned & x p h 4 & x p h 4 aligned Here x= p and p=m v aligned & v^2= h m^2 4 & or & v= 1 2 m h aligned Note: The uncertainty principle in terms of energy and time is given as E t h 4
