An electron is projected with an initial speed v = 2.95 x 105 m/s directly toward a very distant proton that is at rest. Because the proton mass is large relative to theelectron mass, assume that the proton remains at rest. By calculating the work done on the electron by the electrostatic force, determine the distance between the twoparticles when the electron instantaneously has speed 3v.NumberUnitsthe tolerance is +/-2% In crystals of the salt cesium chloride, cesium ions Cst form the eight corners of a cube and a chlorine ion ci is at the cube's center (see the figure). The edge length of thecube is L = 0.39 nm. The Cst ions are each deficient by one electron (and thus each has a charge of +e), and the Cl ion has one excess electron (and thus has a charge of -e). (a) What is the magnitude of the net electrostatic force exerted on the Cl ion by the eight Cst ions at the corners of the cube? (b) If one of the Cst ions is missing, thecrystal is said to have a defect; what is the magnitude of the net electrostatic force exerted on the Cl ion by the seven remaining Cst ions?Cs+(a) NumberUnits(b) NumberUnits

In an evacuated tube, electrons are evacuated through a potential difference of 500V. Calculate: their final speed, and consider whether this depends on the accelerating field being uniform. After this acceleration, the electrons pass through a uniform electric field which is perpendicular to the direction of travel of the electrons as they enter the field. This electric field is produced by applying apotential difference of 10V to two parallel plates which are 0.06m long and 0.2m apart. Assuming that the electric field is uniform and confined to the space between the two plates. Determine the angular deflection of the electron beam produced by field.
