Question
At what angle will the electrons in Example 21-16 leave the uniform electric field at the end of the parallel plates (point P in the figure)? Assume the plates are 5.8 cm long, E = 4.6
Replace the force system acting on the frame by a resultant force. Express your answer to three significant figures and include the appropriate units. F =____________ Determine the angle between the resultant force and the x axis. ? =_____________ Specify where its line of action intersects member AB, measured from point A. d =_____________Explanation / Answer
the deviation suffered by the charged particle along y-axis as it just comes out of the electric field is given by y= (1/2)*a*t^2=(1/2)(eE/m)*(l/v0)^2....
here e=1.6*10^-19 C
E=4.6*10^3 N/C
Vo= 1*10^7 m/sec....
l is length of plates = 5.8 cm =0.058 m
y=0.0135 m = 1.35 m....
tan theta =(y/l)....
theta = tan^-1(23.432)= 87.55 degrees in clock wise direction or -87.55 degrees
