A particle of mass m and charge (-q) enters the region between the two charged plates initially moving along x-axis with speed vx (like particle 1 in Fig.). The length of plate is L and an uniform electric field E is maintained between the plates.
Suppose that the particle in Exercise is an electron projected with velocity vx=2.0×106ms−1. If E between the plates separated by 0.5 cm is 9.1×102 N/C, where will the electron strike the upper plate? (|e|=1.6×10−19C,me=9.1×10−31kg.)
