  • What is the intensity of the electric field in the depletion region of width <img alt="2.5 \times 10^{-7} \mathrm{m}" src="https://entrancecorner.oncodecogs.com/gif.latex?2.5%20%5Ctimes%2010%5

What is the intensity of the electric field in the depletion region of width 2.5 \times 10^{-7} \mathrm{m}  if the potential barrier is 0.50 \mathrm{V} ?

Option: 1

1 \times 10^{6} \frac{V}{m}


Option: 2

2 \times 10^{6} \frac{V}{m}


Option: 3

2 \times 10^{5} \frac{V}{m}


Option: 4

1 \times 10^{-5} \frac{V}{m}

As we know-

 

Electric field  E=\frac{v}{d} 

                      \begin{array}{l}{=\frac{0.5 v}{2.5 \times 10^{-7} m}} \\ \\ {=2 \times 10^{6} m^{-1}}\end{array}

Hence (2) is the correct answer.
