An Electron Enters the Region Between Two Plates Traveling Along

question 38

Multiple Choice

An electron enters the region between two plates traveling along the x-direction with a speed of v = 2.53 * 10⁶ m/s.Both plates are parallel to the x-y plane and are separated by 3.2 cm.The potential of the top plate at z = 3.2 cm is +150 V while the potential of the bottom plate at z = 0 cm is 0 V.What is the magnitude of the magnetic field between the plates that is required so that the electron continues traveling in a straight line along the x-direction in this region?

• C)2.63 * 10^-4 T
• D)1.32 * 10^-3 T
• E)9.45 * 10^-4 T
