Question 1
a) In J. J. Thomson experiment (1897), an electron moving horizontally with a
constant speed vo enters in between the horizontal plates of a capacitor. The
electric field strength between the plates of length L and distance d, is E.
The vertical deviation of the electron at the moment of exit from the field
region is measured to be Y. Derive the expression giving the electron's
charge to mass ratio, i.e. e/m to be 2v,Y/CEL). (Recall that Thomson
received Nobel Prize for his achievement.)
b) Calculate e/m, knowing the following data. E=1.6x10* Newton/Coulomb,
L=10 cm, Y=2.9 cm, v=2.19x10* km/s. (Be careful to use coherent units.)
Determine the gravitational force and the electric force between the electron and the proton inthe hydrogen atom of they are 5.3×10^-11 meters apart. Then calculate the ratio of Fe to Fg.
