A) \[250\times {{10}^{-3}}m/s\]
B) \[25.0\times {{10}^{-3}}m/s\]
C) \[2.50\times {{10}^{-3}}m/s\]
D) \[1.25\times {{10}^{3}}m/s\]
Correct Answer: C
Solution :
Drift velocity \[{{v}_{d}}=\frac{i}{neA}\] \[=\frac{40}{{{10}^{29}}\times 1.6\times {{10}^{-19}}\times {{10}^{-6}}}\] \[=2.5\times {{10}^{-3}}m/s\]You need to login to perform this action.
