A beam of electrons is initially moving along the negative x-axis at 9.18 Mm/s in the positive x-direction. At x = 0 it enters a region where a uniform 1.86-mT magnetic field points in the positive y-direction. The region begins on the y−z plane and extends indefinitely in the x-direction. Find the maximum distance the beam penetrates into the region.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
