A thin metal plate is being bombarded by a perpendicular beal of gas particles from both sides as shown in the figure. The solid dots are representing the melecules hitting from left side and the faint dots are the molecules hitting frm right side. The mass of these gas particles is m=10^(-26)kg and velocity before hitting is v_(0)=5m//s . Volume density of the gas particles on both sides is n=10^(25) per m^(3) . Each beam has an area A=1m^(2) and the collisions are perfectly elatic. What is the external force F (in newton) required to move the plate with a constant velocity v=2m//s

A current i, indicated by the crosses in figure, is established in a strip of copper of height h and width w. A uniform field of magnetic induction B is applied at right angle to the strip. (a) Calculate the drift velocity v_d of the electrons. (b) What are the magnitude and direction of the magnetic force F acting on the electrons? (c) What should the magnitude and direction of a homogeneous electric field E be in order to counterbalance the effect of mangetic field? (d) Calculate voltage V necessary between two sides of the conductor in order to creat this field E Between which sides of the conductor would this voltage have to be applied? (e) If no electric field is applied from the outside, the electrons will be pushed somewhat to one side and therefore will give rise to a uniform electric field E_H across the conductor until the forces of this electrostatic field E_H balance the magnetic forces encountered in part (b). What will be the magnitude and direction of field E_H ? Assume that n, the number of conductor electrons per unit volume is 1.1xx10^(29) m^-3, h = 0.02 m, w= 0.1 cm, i = 50 A, and B=2 T.
