An electron, a neutron(which has zero charge) and a proton are in an electric field generated by charged plates which points in the +x direction. The three particles are sufficiently far apart that their forces on each other are negligible. Assume also that forces other than the electrostatic ones on the three particles are negligible. We know that: (Choose the correct answers) the acceleration of the electron is in the +x direction. the x coordinate of the electron is less...

A helium nucleus (called an alpha particle) contains 2 neutrons and 2 protons with no electrons. If any electrons are added, there is a negligible amount of mass added but obviously one negative charge per electron is added. Three particles are injected into a constant B-field of 2T at a velocity of 3×106ms. The first particle is only the alpha particle (He++), the second particle is a nucleus with 1 electron (He+), and the third particle is a nucleus with...

Quarks and gluons are fundamental particles that will be discussed in Chapter 44. A proton, which is a bound state of two up quarks and a down quark, has a rest mass of mp=1.67×10−27 kg.mp=1.67×10−27 kg. This is significantly greater than the sum of the rest mass of the up quarks, which is mu=4.12×10−30 kgmu=4.12×10−30 kg each, and the rest mass of the down quark, which is md=8.59×10−30 kg.md=8.59×10−30 kg. Suppose we (incorrectly) model the rest energy of the proton...
