BackA proton is fired with a speed of 1.0×106 m/s through the parallel-plate capacitor shown in FIGURE P31.29. The capacitor's electric field is E =(1.0×105 V/m, down). How does an experimenter in the proton's frame explain that the proton experiences no force as the charged plates fly by?
Muons ( mass = 207 times the electron mass, same charge -e ) are accelerated horizontally by 65 kV. They then pass through a uniform magnetic field B for a distance of 3.8 cm, which deflects them upward so they reach a detector 22 cm away, 11 cm above their original direction. Estimate the value of B.
A 3.40-g bullet moves with a speed of 155 m/s perpendicular to the Earth’s magnetic field of 5.00 x 10⁻-5 T. If the bullet possesses a net charge of 18.5 x 10-9 C, by what distance will it be deflected from its path due to the Earth’s magnetic field after it has traveled 1.25 km?
An electron moves with velocity in a magnetic field . Determine the magnitude and direction of the force on the electron.
(II) An electron experiences the greatest force as it travels 2.8 x 106 m/s in a magnetic field when it is moving northward. The force is vertically upward and of magnitude 7.4 x 10-13 N. What is the magnitude and direction of the magnetic field?
(I) Alpha particles (charge q = +2e, mass m = 6.6 x 10-27 kg) move at 2.2 x 106 m/s. What magnetic field strength would be required to bend them into a circular path of radius r = 0.14 m?
An electron is projected vertically upward with a speed of 1.70 x 106 m/s into a uniform magnetic field of 0.550 T that is directed horizontally away from the observer. Describe the electron’s path in this field.
Determine the magnitude and direction of the force on an electron traveling 7.75 x 105 m/s horizontally to the east in a vertically upward magnetic field of strength 0.65 T.
