The figure shows vertical parallel plates of length L=5 cm separated by 4 cm. Electrons (mass me = 9.11x10-31 kg) enter vertically at a speed v0 = 1x106 m/s. %3D The potential difference between the plates is initially set to VA-VB = +1OV. At this potential difference the electrons impact one of the plates. (a) Which plate (A/B) is hit by the electrons?Ealculate the speed of the electrons as they impact the corresponding plate.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
