A) \[36{}^\circ C\]
B) \[83{}^\circ C\]
C) \[63{}^\circ C\]
D) \[33{}^\circ C\]
Correct Answer: C
Solution :
[c] \[{{v}_{d}}=\frac{1}{neA}\]here, \[I=5.4A,n=8.4\times {{10}^{28}},\] \[\text{per }{{\text{m}}^{\text{3}}}\] \[\text{A=1}{{\text{0}}^{-6}}{{m}^{2}},e=1.6\times {{10}^{-19}}C\] \[\therefore {{v}_{d}}=\frac{5.4}{8\times {{10}^{28}}\times 1.6\times {{10}^{-19}}\times {{10}^{-6}}}=0.4mm/s\]
