A parallel plate capacitor with plates of length l is included in a circuit as shown in figure-3.164. The EMF of the source is `epsilon`, its internal resistance is r and the distance between the plates is d. An electron with a velocity u files into the capacitor, parallel to the plates . What resistance R should be connected in parallel with the capacitor so that the electron files out of the capacitor at an angle of `37^(@)` to the plates? Assume that circuit is in steady state. Given values of parameters as `l=91cm epsilon=3V,r=2Omega,d=(1//3)mm,u=4xx10^(7)m//s m_(e)=9.1xx10^(-31)kg` and `e=1.6xx10^(-19)C`.

Answer

3 ohm
