1. The problem statement, all variables and given/known data: Velocity of an electron at point A1 is Vo where cross sectional area is A. The velocity of electron at the end of contraction at point B where cross sectional area is 2A is V1.Find correct option a)V1< V0 b)V1= V0 c)V1> V0 d)V1<=V0/2 I have attached a picture of the question as well. Please refer to it for the diagram. (Question 9) 2. Relevant equations: I failed to relate it with electrostatics 3. The attempt at a solution: I feel the given information is insufficient to determine the answer. something about the charge of the cross sectional area or atleast something more should have been mentioned.
