5. An electron carrying charge -9 (where q=1.602e-19 C) is moving along the x axis in the +x direction with a velocity ū(x, y, z) = 5 x 107 cm/s. a. We want to make the electron to curve to the right and eventually go in a circle clockwise in the xy plane by applying a magnetic field. To achieve that, the magnetic field should exert a force on the electron that is perpendicular to its direction of motion. Which...

3R MC 12 Two identical solenoids are connected to each other so that they carry the same current, and are inserted through two loops in an electrical circuit, as shown left diagram. The solenoids are oriented such that when you loolk from one end, the currents are circulating in opposite directions, as showin in the second diagram. For a period of time, the current flowing through the solenoids is changing in a steady linear manner: It) ~ t. During this...

Constants Any event can be considered from different perspectives. In particular, the description of the motion of a given object would depend on the motion of the person describing the motion, the observer. Any such observer, equipped with a coordinate system anda stopwatch, forms a trame of reterence. Usually, we assume that a trame of reterence is attached to some object. For instance, "the trame of reterence of earth" means the observer is at rest relative to earth. In this...

27B -- Experiment: Magnetic Force on a Moving Charge - qolme Objective: In this module you will observe the trajectory of an electron beam in a uniform magnetic field oriented in various ways to the electron velocity. You will then use your observation of the radius of the electron trajectory to measure the charge to mass ratio for an electron. Equipment: One elm apparatus (Lurge mounted glass bulb with Helmholtz coils); one Leybold or PASCO power supply for electron gun...

please write neatly
Practice drawing FBDs You will first identify all the forces using the approach above (Foblect 1-object 2) and then switch to mg, N, 1, e H. Each description below indicates the object of interest via bold italics. Draw a picture of the situation, in which you identify contact points. Then, following the same steps outlined above, draw a FBD on the object of interest. All forces should be written as above (Fobiect 1-+oblect 2). Make sure the...
