As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity vv. As it passes through the region x -O to x- d, the electron experiences acceleration aal+aj, where a, and a, are constants. For the case v,- 2.00 x 10 m/s, a, 7.52 x 1014 mys, and a, 1.68 x 105 m/s?, determine the following at xd0.0100 m. (a) the position of the electron m (b) the velocity of the electron m/s i+ m/s ) (c) the speed of the electron m/s (d) the direction of travel of the electron (1.e. the angle between its velocity and the x axis)

Question
It is not possible to see very small objects, such as viruses, using an ordinary light microscope. An electron microscope can view such objects using an
electron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellular
structures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist of
electric and magnetic fields that control the electron beam.
As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial
velocity v,- vi. As it passes through the region x = 0 to x-d, the electron experiences acceleration a = a,i + aj, where a, and a, are constants. For
the case v, = 2.00 x 10 m/s, a,- 7.52 x 1014 m/s, and a,- 1.68 x 10o15 m/s?, determine the following at x = d- 0.0100 m.
