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?

Question

Quizplus · Accepted Answer

The correct answer is A because the magnetic field required to keep the electron traveling in a straight line is given by:B = (m * v) / (q * d)where:m is the mass of the electronv is the velocity of the electronq is the charge of the electrond is the distance between the platesPlugging in the given values, we get:B = (9.11 * 10^-31 kg * 2.53 * 10^6 m/s) / (1.602 * 10^-19 C * 0.032 m) = 1.85 * 10^-3 T
