(a) The figure below shows two parallel conducting rails 15.2 cm apart, connected by a resistor with resistance R₂ = 5.00 Q. Two metal rods with resistances R₁ = 11.40 and R₂ = 15.0 (2 slide along the rails with negligible friction. Rod R₁ slides to the left at constant speed v₁ = 4.00 m/s, while rod R₂ slides at speed v₂ = 2.00 m/s. The rods and rails are in the presence of a uniform magnetic field pointing into the page, perpendicular to the plane of the rails, with a magnitude of Bin = 0.0100 T. +5 x x x x x x x x x x x x x x x x x x x x x x x x x x upward x x x ---Select--- X * x x x x x x x x Rg x x x x x R₁ R₂ What are the magnitude (in μA) and direction of the current through resistor R₂? μA magnitude direction x x x x (b) What If?

An electron (q=−1.602×10−19[C]) moves a distance d=2.50[m] in a linear accelerator under a uniform external electric field of magnitude E→=3.50×10^7[N/C]. What is the energy gained by the electron in electron volts?
Forces in an atom. The particles in the nucleus of an atom are approximately 10- 15 m apart, while the electrons in an atom are about 10- 10 m from the nucleus. (a) Calculate the electrical repulsion between two protons in a nucleus if they are 1.00 x 10- 15 m apart. If you were holding these protons, do you think you could feel the effect of this force? How many pounds would the force be? (b) Calculate the electrical attraction that a proton in a nucleus exerts on an orbiting electron if the two particles are 1.00 x 10- 10 m apart. If you were holding the electron, do you think you could feel the effect of this force?

ou have a summer job as an assistant technician for a telephone company in California.During a recent earthquake, a 1.0-mile long underground telephone line is crushed atsome point. This telephone line is made up of two parallel copper wires of the samediameter and same length, which are normally not connected. At the place where theline is crushed, the two wires make contact. Your boss wants you to find this placeso that the wire can be dug up and fixed. You disconnect the line from the telephonesystem by disconnecting both wires of the line at both ends. You then go to one end ofthe line and connect one terminal of a 6.0-V battery to one wire, and the other terminalof the battery to one terminal of an ammeter. When the other terminal of the ammeteris connected to the other wire, the ammeter shows that the current through the wire is1.0 A. You then disconnect everything and travel to the other end of the telephone line,where you repeat the process and find a current of 1/3 A.
Two small metallic spheres, each of mass m = 0.204 g, are suspended as pendulums by light strings of length L as shown in the figure below. The spheres are given the same electric charge of 6.8 nC, and they come to equilibrium when each string is at an angle of 8 = 5.05° with the vertical. How long are the strings? m m L 8 m

In an inkjet printer, letters and images are created by squirting drops of ink horizontally at a sheet of paper from a rapidly moving nozzle. The pattern on the paper is controlled by an electrostatic valve that determines at each nozzle position whether ink is squirted onto the paper or not. Figure 9 Do 163 Ē T 1 of 1 The ink drops have a mass m = 1.00×10-11 kg each and leave the nozzle and travel horizontally toward the paper at velocity = 24.0 m/s. The drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. The drops then pass between parallel deflecting plates of length Do = 1.50 cm, where there is a uniform vertical electric field with magnitude E= 8.15x104 N/C. (Figure 1) Part A If a drop is to be deflected a distance d = 0.250 mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? Assume that the density of the ink drop is 1000 kg/m³, and ignore the effects of…
