Uncertainty in position is twice the uncertainty in momentum. Uncertainty in velocity is?

S. Saha Student Expert 5th Apr, 2020
Let uncertainty is position denoted by (del)x and uncertainty in momentum denoted by (del)p.

(del)x is equal to 2 * (del)p
Or, (del)x * (del)p = h/4 pie
Or, 2 * (del)p^2 = h/4 pie
Then solve it.
(del)p will be equal to (1/root 2*2) * (root over of h/pie).
