WebQuestion: Question 5: Charged Particle in Cross Electric and Magnetic Fields. A particle of charge \( q \) and mass \( m \) is moving in a uniform magnetic field \[ \vec{B}=B \hat{z} \] and an electric field, directed radially outward or inward from a central wire along the \( \hat{z} \)-axis \[ \vec{E}=\frac{a}{r} \hat{r}_{1} \] where \( r \) is the distance from the WebWe can express the electric force in terms of electric field, \vec F = q\vec E F = qE. For a positive q q, the electric field vector points in the same direction as the force vector. The equation for electric field is similar to Coulomb's Law. We assign one of the q q 's in the … For the electric force, the force-carrier is the photon, which is sort of like a "chunk" of … An electric charge can exist by itself. The strength of the electric field falls off as … F ⃗ \vec F F F, with, vector, on top is the electric force, directed on a line between …
