Texts: Please only give the right answer. I have been getting wrong answers. I will upvote and no ChatGPT. Shown in yellow in the figure below is a region of the uniform magnetic field of width a = 1.26 cm that is used to deflect a beam of accelerated electrons entering this region normally with speed v = 7.05 x 10^6 m/s. After leaving the deflection region, electrons hit the screen, distance b = 10.9 cm away, to produce an image. When the field is zero, the electrons would hit the screen in the center, at point O. With the field B = 27.4 G, electrons hit the screen at point P, distance d above point O. Find this displacement d caused by the magnetic deflection: d = cm.

When speeds v are high enough to compare with the speed of light c, however, K(v) = moc^2 (1 - v^2/c^2)^(-1/2) 1)
