I just want to ask that if a student of cbse 2020 predict the score of chem-50/70 bio 55/70 and in physics he just predicted 21/70 means he need 2 marks to pass in the subject. So CBSE will give gracing marks??

Hii Harit!
CBSE doesn't disclose such information about the results of any particular student or field for that matter. So, it is not certain if you get grace marks or not. Still, if you fail, you can attempt a re-examination and score good to pass in that particular subject.

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).
