1. Shown in yellow in the figure below is a region of the uniform magnetic field of width a=1.18 cm that is used to deflect a beam of accelerated electrons entering this region normally with speed v=11.6 × 106 m/s. After leaving the deflection region, electrons hit the screen, distance b=13.6 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=46.3 G, electrons hit the screen at point P, distance d above point O. Find this displacement d caused by the magnetic deflection: d= _____ cm
