An electron is accelerated fromrest through potential difference V and then enters a region of uniform magnetic field, where it undergoes uniform circular motion. Figure 28-37 gives the radius rof that motion versus V1/2.The vertical axis scale is set by rs= 3.9 mm, and the horizontal axis scale is set by Vs1/2= 32.4 V1/2. What is the magnitude of themagnetic field?
Chapter 28, Problem 020 An electron is accelerated from rest through potential difference V and then enters a region of uniform magnetic field, where it undergoes uniform circular motion. The figure gives the radius r of that motion versus Vi/2. The vertical axis scale is set by rs= 2.7 mm, and the horizontal axis scale is set by Vs1/2= 40.7 Vi/2, What is the magnitude of the magnetic field? V/2 (v/2) (unuu)
Chapter 28, Problem 020 Your answer is partially correct. Try again. An electron is accelerated from rest through potential difference V and then enters a region of uniform magnetic field, where it undergoes uniform circular motion. The figure gives the radius r of that motion versus v1/2. The vertical axis scale is set by r= 2.9 mm, and the horizontal axis scale is set by V, 1/2= 25.7 v1/2. What is the magnitude of the magnetic field? r (mm) v1/2...
• An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was before entering region 2. (a) Draw a physical representation of this situation, complete with the direction of the electric and...
Question 7 /1 View Policies Current Attempt in Progress In the figure, an electron with an initial kinetic energy of 3.60 keV enters region 1 at time t 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.0130 T. The electron goes through a half-circle and then exits region 1, headed toward region 2 across a gap of 22.0 cm. There is an electric potential difference AV 1900 V across the gap, with a polarity...
