Suppose a particle with a charge-mass ratio (q/m) of 1kg/C moves with a velocity 10 m/s parallel (v = 10m/s i) to a parallel plate capacitor with length of 1m. When it exits, the particle has dropped 1 meter from its original height (Δy = -1m j). Suppose the particle in under the influence of a uniform magnetic field that is perpendicular to both the velocity of the particle and the electric field from the capacitor, and has a magnitude of 1T (B = 1T k). What is the magnitude of the electric field?

In the figure, an electron accelerated from rest through potential difference V1-1.26 kV enters the gap between two parallel plates having separation d = 19.6 mm and potential difference V2- 52.4 V. The lower plate is at the lower potential. Neglect fringing and assume that the electron's velocity vector is perpendicular to the electric field vector between the plates. In unit-vector notation, what uniform magnetic field allows the electron to travel in a straight line in the gap? Number ( o ĵ+ i R) Units mT 124.7

As shown in the figure, an electron is fired with a speed of 3.43 x 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.20 m. There is a magnetic field in the region between the plates and, as shown, it is directed into the plane of the page (perpendicular to the velocity of the electron). Determine the magnitude of the magnetic field so that the electron just misses colliding with the opposite plate. electron

A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from a velocity selector at a speed of 3.00 x 105 m/s and enter a uniform magnetic field of 0.375 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by ions of 235U and 238U? The mass of a 235U ion is 3.902 x 10-25 kg, and the mass of a 238U ion is 3.952 x 10-25 kg, while both types have a charge of 1.602 x 10-19 C. A mass spectrometer (schematic). Charged particles are first sent through a velocity selector. They then enter a region where a magnetic field B causes positive ions to move in a semicircular path and strike a photographic film at P.
