A positively charged particle is traveling in the positive direction along the line \(y=x\) in the presence of a constant \(B\) field pointing in the positive \(x\) direction. In what direction is the Lorentz [Iohr-ENZ] force on the particle pointing?
NEGATIVE Z7) Energy - Multiple Choice Researchers at Oak Ridge National Lab use pulsed laser light to induce thermal stress. This enables them to study the behavior of what type of excitation that plays an important role in many of the physical properties of solids?
