Part B A problem of practical interest is to make a beam of electrons turn a 90° corner. This can be done with the parallel-plate capacitor shown in (Figure 1). An electron with kinetic energy 4.0x10-17 J enters through a small hole in the bottom plate of the capacitor. What strength electric field is needed if the electron is to emerge from an exit hole 1.0 cm away from the entrance hole, traveling at right angles to its original direction? Hint: The difficulty of this problem depends on how you choose your coordinate system. Express your answer to two significant figures and include the appropriate units. Figure 1 of 1

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.
