Viewers of Star Trek have heard of an antimatter drive on the Starship Enterprise. One possibil- ity for such a futuristic energy source is to store antimatter charge particles in a vacuum chamber, circulating in a magnetic field, and then extract them as needed. Antimatter annihilates normal matter, producing pure energy. a) What strength magnetic field is needed to hold antiprotons, moving at 5.0 × 107 m/s in a circular path 2.00 m in radius? Antiprotons have the same mass as protons (mp = 1.673 × 10−27 kg) but the opposite (negative) charge. b) Is this field strength obtainable with today’s technology or is it a futuristic possibility?

We have discussed in the lectures that on the equator earth’s magnetic field is approximately 50µT in strength andpoints northward.

A common way to focus a beam of charged particles is to use an electric field and a magnetic field together. Based on the relative strength and orientation of the two fields, you can tune the Coulomb and Lorentz forces to direct the beam of particles. This technique is common in mass spectrometers and scanning electron microscopes. You want to focus a beam of positively charged particles moving in the -z direction. The particles have a mass of 3.30e-23 kg and you orient a 0.341 T magnetic field in the +x direction. What direction do the particles feel the Lorentz force from the magnetic field? The particle is moving with a velocity of 1.97e+05 and has a charge of 1.00e-16 C. What is the magnitude of the Lorentz force on the particle S in Newton?

A positron ( e+) and a electron (e-) are ejected at the same speed from a subatomic particle that is decaying. they are both ejected at the exact same speed. however they are ejected in directions that are opposite to eachother. assume there is a 1.20 mT magneticfield that is uniform acting perpendicular to the initial velocities, how long would it take the positron and electron to collide into eachother? You MUST Draw the trajectories of moving particles.
