Consider the path of the proton (q = 1.602 × 10−19 C, m = 1.673 × 10−27 kg) in a uniform electric and magnetic field. Both fields are in the z direction, B⃗ = B0k? and E⃗ = E0k?, where B0 = 55 mT and E0 = 180 V / m. At time t = 0, the proton moves at v⃗ = v0?ı, v0 = 150 km / s. Based on this information, what kind of orbit does the proton...
A beam of photons (q = +1.6 x 10^-19 C) is moving with various speeds in the positive x direction (to the right). It enters a region where there is a uniform magnetic field of magnitude 0.25T pointing in the negative z direction (into the page). a) The protons feel a force due to this magnetic field. Explain why, and indicate the direction of the force. b) Not all protons will feel a force of the same magnitude. Why? c)...

(ex) The electric field is 1.20 times 10^6 N/C between plates 1 and 2, but is zero everywhere else in the figure. The magnetic field is 0.600 T everywhere in the figure. After passing straight through the region between the plates, aluminum ions enter the region with only a magnetic field, move in a circular path of radius 0.899 m there, and finally hit the photographic plate. a) The region between plates 1 and 2 is a "velocity selector": Only...

A proton (m= 1.67e-27 kg) is accelerated from rest through a potential difference of 11.5 kV before entering a velocity selector. If the B- field of the velocity selector is perpendicular to the velocity and the electric field (E) has a magnitude of 3.5e6 N/C, what is the required magnitude of the magnetic field (B) if the proton is undeflected?
PROBLEM 1 – A velocity selector (Wien Filter) has an electric field of magnitude 2470 N/C, directed vertically upward, and a horizontal magnetic field that is directed to the south. Charged particles, traveling east at a speed of 6.50 × 103 m/s, enter the selector and are able to pass through undeflected. When a different charged particle with an electric charge of +4.00 × 10-12 C enters the selector traveling east, the net force acting on it is 1.90 ×...
