1.	A potential barrier of 0.5 V exists across a p-n junction (i) If the depletion region is 5 x 10^7m wide. What is the average intensity of the electric field in this region ? (ii) An electron with speed 5 x 10^{5 } m/s approachesthe p-n junction from the n-side with what speed will it enter the p-side?
