A DC voltage of 10 V is applied across an n-type silicon bar having a rectangular cross-section and a length of 1 cm as shown in figure. The donor doping concentration ND and the mobility of electrons μn are 1016 cm−3 and 1000 cm2 V−1 s−1 respectively. The average time (in μs) taken by the electrons to move from one end of the bar to other end is __________.
Correct : 100
