1.	The velocity of an electron at point `A_(1)` is `V_(0)` where cross sectional areas is `A`. The velocity of electron just the end of contraction at point `B`, where cross sectional area is `2A` is `V_(1)`. Find the correct option: A. `V_(1) lt V_(0)`B. `V_(1)=V_(0)`C. `V_(1) gt V_(0)`D. `V_(1)=(V_(0))/(2)`
Answer» Correct Answer - c As the electrons comes near the throat, positive charges are induced on the throat. The induced charges attract the electron and velocity increases. So `V_(1)gtV_(0)`.
