A) \[19.2\times {{10}^{-2}}m\]
B) \[5.76\,\times {{10}^{-2}}\,m\]
C) \[1.92\times {{10}^{-2}}m\]
D) \[3.84\times {{10}^{-2}}m\]
Correct Answer: C
Solution :
\[\Delta x.\Delta v\ge \frac{h}{4\pi m}\] \[\Delta x=\frac{6.63\times {{10}^{-34}}}{4\times 3.14\times 9.1\times {{10}^{-31}}\times 300\times 0.001\times {{10}^{-2}}}\] \[=0.01933\] \[=1.93\times {{10}^{-2}}\]
