B V2 17 A positively charged particle moves through a region with a uniform electric field pointing toward the top of the page and a uniform magnetic field pointing into the page. The particle can have one of the four velocities shown in the figure. (a) Rank the four possibilities in order of increasing magnitude of the net force the...
I need help on this one, please and thank you.
The circuit in the figure consists of switch S, a 6.00 V ideal battery, a 30.0 Mohm resistor, and an airfilled capacitor. The capacitor has parallel circular plates of radius 5.70 cm, separated by 3.50 mm. At time t = 0, switch S is closed to begin charging the capacitor....

The conducting rod bd shown in the figure makes contact with metal rails ab and cd. The apparatus is in a uniform magnetic field of 0.8 T. perpendicular to the plane of the figure. Length 1 = 98 cm. If the resistance of the circuit is 1.50 Ohm (assumed to be constant), find the force (magnitude and directions required...
Compute the dielectric constants of the media in the following scenarios: i. The electric potential due to a 1 ∗ 10-9C charge 1 meter away on a test charge is 9 volts. What might be the medium in this interaction? ii. The electrostatic energy is 2.93 ∗ 10-20J for two electrons one angstrom apart. What might be the medium in...
Will give an up vote only if detailed explanation is given.
Thank you.
10. (8 points) Which equation correctly describes the electromagnetic wave shown to the right? a. Ex = E. sin(kz + wt) b. Ey = E. sin(kz - wt) c. By = Bo sin(kz - wt) d. By – Bo sin(kz + wt)
i) (4 pts) In Quantum Mechanics, electromagnetic radiation, such as radio waves, consists of wave packets called photons. It is not known how many wavelengths are in a single photon, but some experimental estimates put it at around a million. Make this assumption and calculate how long, to the nearest day, it would take the piece of ebonite to generate...
A proton (charge = +e) instantaneously is moving north in a region where there is a uniform magnetic field pointing downward. At this instant, in what direction will the proton be deflected? to the east no direction (zero force) upward to the west downward

A plane wave is incident on a dielectric slab of permittivity er and thickness d at an incidence angle θο, where d A)/(4 Ver) and λο is the free-space wavelength of the incident wave, as shown in the accompanying figure. If free-space exists on both sides of the slab, find the reflection coefficient of the wave reflected from the front...
