(5) (10 pts.) A uniform magnetic field of magnitude 0.80 T in the negative z- direction is present in a region of space, as shown in the figure. A uniform electric field is also present. An electron that is projected with an initial ve- locity in the positive x-direction passes through the region without deflection. What is the magnitude and direction of the electric field in the region? y X X X X Z X B = 0.80 T O X Vo X X X XA particle with charge 6.98 x 10 8 C is moving in a region where there is a uniform 0.810 T magnetic field in the +x-direction. At a particular instant, the velocity of the particle has components Vr = -1.71 x 104 m/s, Vy = 2.98 x 104 m/s and v2 - 5.12 x 104 m/s. What are the components of the force on the particle at this time?As the particle ( i ) goes through electric and magnetic field . total Lorentz force on changed particle ( @ ) F = q E + U'X B') if the particle does not deflect then F 20 E = - VXB V - tivo m/s 2 - Vo (0 .80 ) ( EX - * ) 3 = - K O. 80 T = - 0.80V. 3 .
