Question

Hey how would I solve this? The drawing shows an electron entering the lower left side ofa parallel plate capacitor and exiting at the upper right side. Theinitial speed of the electron is 1.88 x 106 m/s. Thecapacitor is 2.00 cm long, and its plates are separated by 0.150cm. Assume that the electric field between the plates is uniformeverywhere and find its magnitude. Thanks! Hey how would I solve this?

Explanation / Answer

This is like a horizontal projectile.    x = u.t; t = x/u =0.02/1.88x106 =1.064x10-8 s     Y = 0.5a.t2 Acceleration,          a =2.y/t2 =2x0.0015/(1.064x10-8)2            = 0.2651x1014 m/s2 F = eE = m.a           E =m.a/e             = (9.1x10-31x0.2651x1014)/1.6x10-19              =150.8 N/C Acceleration,          a =2.y/t2 =2x0.0015/(1.064x10-8)2            = 0.2651x1014 m/s2 F = eE = m.a           E =m.a/e             = (9.1x10-31x0.2651x1014)/1.6x10-19              =150.8 N/C
