Transcribed Image Text:
The figure shows a mass spectrometer where a negatively charged ion (q = -2e, m = 4.25x10-26 kg) moves between the plates of the velocity selector and then enters the deflection chamber. The electric field between the plates is E= 700 V/m and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.850 T directed into the page. a. Inside the velocity selector: (i) What is the direction of the electric force? (ii) What is the direction of the magnetic force? (iii) Calculate the speed of the ion so that it is moving in a straight line parallel to the plates. xxx x x X x x x x x + + + 15 E x x deflection chamber 1 XA 1 XA x 9 x T x x x velocity selector The figure shows a mass spectrometer where a negatively charged ion (q = -2e, m = 4.25x10-26 kg) moves between the plates of the velocity selector and then enters the deflection chamber.
