JEE Main 2006 — Structure Of Atom Question with Solution
From: AIEEE 2006
Question

Show full solutionCorrect option: A
Correct answer
A1.92 10-2 m
Step-by-step explanation
% error in velocity =
0.001 =
V = 3 10-3
According to Heisenberg uncertainty principle,
= 1.92 10-2 m
0.001 =
V = 3 10-3
According to Heisenberg uncertainty principle,
= 1.92 10-2 m
