If the uncertainty in velocity of electron ( v ) is 0.1 ~m / s , the uncertainty in its position ( x) is (given: m_e=9.1 10⁻³¹ ~kg )
Options
- A2.02 10⁻⁴ ~m
- B4.04 10⁻⁴ ~m
- C5.79 10⁻⁴ ~m
- D8.42 10⁻⁴ ~m
Correct answer
C. 5.79 10⁻⁴ ~m
Step-by-step solution
x P = x m v = h 4 = 6.626 10⁻³⁴ 4 3.14 aligned & =5.27 10⁻³⁵ & x= 5.27 10⁻³⁵ (9.1 10⁻³¹ )(0.1) =5.79 10⁻⁴ ~m aligned
