Chapter 37: Q. 6 (page 1081)

FIGURE Q37.6 shows a magnetic field between two parallel, charged electrodes. An electron with speed vopasses between the plates, from left to right, with no deflection. If a proton is fired toward the plates with the same speed vo,will it be deflected up, deflected down, or pass through with no deflection? Explain.

Short Answer

Expert verified

Proton will pass through plates with no deflection.

Step by step solution

01

Given information

We have given that an electron with speed v0 is passed through oppositely charged plates having magnetic field between them . The electron passes left to right without deflection.

02

Explanation

We all know that charge on electron and proton is same. Now, the electron and proton both are fired towards the plates having uniform magnetic and electric field with same velocities and parallel to the plates due to which force applied by magnetic field will be same as that applied by electric field but in opposite direction. So the path of proton will be same as that of electron i.e. straight without any deflection.

Your friend flies from Los Angeles to New York. She carries an accurate stopwatch with her to measure the flight time. You and your assistants on the ground also measure the flight time.

a. Identify the two events associated with this measurement.

b. Who, if anyone, measures the proper time?

c. Who, if anyone, measures the shorter flight time?

Suppose that in a hypothetical oil-drop experiment you measure the following values for the charges on the drops:3.39×10-19C,6.65×10-19C,2.66×10-19C,10.64×10-19Cand9.31×10-19C. What is the largest value of the fundamental unit of charge that is consistent with your measurements?

Two of the wavelengths emitted by a hydrogen atom are 102.6nmand1876nm.

a. What are the mand nvalues for each of these wavelengths?

b. For each of these wavelengths, is the light infrared, visible, or ultraviolet?

An electron in a cathode-ray beam passes between 2.5cm-long parallel-plate electrodes that are 5.0mm apart. A 2.0mT, 2.5-cm-wide magnetic field is perpendicular to the electric field between the plates. The electron passes through the electrodes without being deflected if the potential difference between the plates is 600V.

a. What is the electron’s speed?

b. If the potential difference between the plates is set to zero, what is the electron’s radius of curvature in the magnetic field?
