A) 1.92 cm
B) 7.68 cm
C) 0.175 cm
D) 3.84 cm
Correct Answer: C
Solution :
[c] \[\Delta x.\Delta p=\frac{h}{4\pi }\] or \[\Delta x.m\Delta v=\frac{h}{4\pi };\] \[\Delta v=\frac{0.011}{100}\times 3\times {{10}^{4}}=3.3cm{{s}^{-1}}\] \[\Delta x=\frac{6.6\times {{10}^{-27}}}{4\times 3.14\times 9.1\times {{10}^{-28}}\times 3.3}=0.175cm\]You need to login to perform this action.
