6 Figure 28-26 shows crossed uniform electric and magnetic fields E and B and, at a certain instant, the velocity vectors of the 10 charged particles listed in Table 28-3. (The vectors are not drawn to scale.) The speeds given in the table are either less than or greater than E/B (see Question 5).

Fields of an electron At a particular instant a proton is at the origin, moving with velocity m/s. At this instant: (a) What is the electric field at location m, due to the proton? E = N/C (b) What is the magnetic field at the same location due to the proton? B= T

(unrealistic) E/M Forces 6. A particle of charge q = 0.25C and mass m = 1.0kg is moving with a velocity of v = (2,0,0)m/s. The (8,8,8)N/C and a magnetic field of B = (0,0, –2)T. charged particle finds itself in an electric field of E What will be the initial vector acceleration of the particle?
