Q1. A space traveller whose mass is 122 kg leaves earth. What are his weight and mass on earth and in interplanetary space where there are no nearby planetary objects?
Q2. It is not possible to see extremely small objects, such as viruses, using an ordinary light microscope. An electron microscope can view such objects using 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 instance of the manipulation of an electron beam, consider an electron travelling away from the origin along the x axis in the xy plane with first velocity v = vi. As it passes through the region x = 0 to x = d, the electron experiences acceleration a = ax + ay, where ax and ay are constants. For the case vi = 1.94 107 m/s, ax = 7.13 1014 m/s2, and ay = 1.74 1015 m/s2, determine the following, at x = d = 0.0100 m.
(a) position of the electron
yf =
Your response differs significantly from the correct answer. Rework your solution from beginning and check each step carefully.
(b) Velocity of the electron
(c) speed of the electron
(d) direction of travel of the electron (as in the angle between its velocity and the x axis)
