A negatively charged ion with an excess electron moving with a velocity vx = 1.095 x103 m/s is introduced into a magnetic field Bz = 4 mTesla perpendicular to the ion’s direction of motion. The ion travels in a semi circle of diameter d = 8 cm before striking a detector. What is the ion? Select one: a. 14N b. 12C c. 16O d. 32S

0.01 T magnetic field points south and downward, 45o below the horizontal. A proton travels south at 500 m/s. What is the force on the proton? In the figure below, east points out of the page and west points into the page.

I'm having trouble with some questions. They're listed below. 1) The particle in the figure below has a charge of 8.00 ⨯ 10-6 C, a speed of 1.20 ⨯ 103 m/s, and it is in a uniform magnetic field, directed into the page, of 2.50 ⨯ 10-2 T. The initial velocity of the particle is directed at 30° below the positive x-direction, assuming the x-direction is toward the right. What is the magnitude of the magnetic force acting on the particle?  The image is the first image that shows up with the 9 dots. As for the other question I've already solved for two parts and am just having some trouble for part C.  2) Particle 1 has a charge of +40.0 microcoulombs, and a mass of 2.40 milligrams. Particle 1 also has a speed, when it enters region A, of 6.00 m/s.  a) If region A is a square measuring 30.0 cm on each side (the other regions have the same size as region A, of course), what is the magnitude of the magnetic field in region A- I found it to be 3.6 Teslas b) From the instant particle 1 enters…

Electrons are accelerated from rest in a CRT. These electrons now pass through a magnetic field of 2.70 x 10-2 T and through an electric field of 5.50 x 105 N/C. The fields are perpendicular to each other. If the electrons are not deflected, assuming the electrons are traveling perpendicular to these fields, what is the potential difference across the CRT?
