A) \[\text{1}{{\text{0}}^{\text{-20}}}\,\text{m}\]
B) \[\text{1}{{\text{0}}^{\text{-16}}}\,\text{m}\]
C) \[\text{1}{{\text{0}}^{\text{-12}}}\,\text{m}\]
D) \[\text{1}{{\text{0}}^{\text{-8}}}\,\text{m}\]
Correct Answer: B
Solution :
Given, \[m=11\times {{10}^{-12}}kg\] and \[v=6\times {{10}^{-7}}\,\,m/s\] de-Broglie wavelength \[\lambda =\frac{h}{mv}\] \[\lambda =\frac{6.67\times {{10}^{-34}}}{11\times {{10}^{-12}}\times 6\times {{10}^{-7}}}\] \[\lambda =\frac{1}{10}\times {{10}^{-15}}={{10}^{-16}}m\]
