A) \[125\times {{10}^{-3}}m/sec\]
B) \[12.5\times {{10}^{-3}}m/sec\]
C) \[1.25\times {{10}^{-3}}m/sec\]
D) \[1.25\times {{10}^{-4}}m/sec\]
Correct Answer: C
Solution :
\[{{v}_{d}}=\frac{i}{nAe}=\frac{20}{{{10}^{29}}\times {{10}^{-6}}\times 1.6\times {{10}^{-19}}}\]\[=1.25\times {{10}^{-3}}m/s\]You need to login to perform this action.
