When vectors representing the silk forces are added, the vector addition fur given below results. 200 cm 1.00 cm wool glass Holds electrons loosely static force on Charge C expressed in scientific notation is a.bc x 10 N/C. The values of a, b, c, and d, respectively, are _. (Record your 4 digits answer) Dome of Your answer: 1. Refer to the above Electrostatic Series table. When ebonite is rubbed with fur, Metal 78.09 which of the following is the most likely result? sphere Using the information from the above question and the following additional both ebonite and fur become positively charged information to answer the next question. ebonite becomes negatively charged and fur becomes positively charged The spheres are touched toge following order. t grounding, in the ebonite becomes positively charged and fur becomes negatively charged The mass of the metal sphere is 3.55 x 10-5 kg. The magnitude of the electric Spheres K and L force, Fe, expressed in scientific notation, is a.bc x 10"d N. The values of a, b, c, Step II Spheres K and M both ebonite and fur become negatively charged Step III Spheres L and M and d are . (Record your 4 digits answer) Which of the following rows indicates the final charge present on each sphere? Use the following information to answer the next question Your answer:DO Sphere K: Ox Sphere L: Ox Sphere M: Ox Determining the Charge on a Sphere 4. One charged object exerts a force, Fe, on a second charged object. If the distance Sphere K: -x/4 Sphere L: +x/2 Sphere M: +x/2 Given an ebonite rod, fur, and an electroscope, steps in an experimental procedure to determine the unknown charge on a sphere, are stated below: between the two charged objects is doubled, and the charge on one of the objects is halved, then the electric force that one charge exerts on the other is Sphere K: +x/2 Sphere L: -x/4 Sphere M: -x/4 Bring the electroscope close to the sphere with an unknown charge Sphere K: +x/2 Sphere L: -3/4x Sphere M: -3/4x Touch the ebonite rod to the electroscope. - F Rub the ebonite rod with the fur. Use the following information to answer the next two questions Observe the leaves on the electroscope I F A student has three identical spheres, K, L, and M, on insulated stands equally and qM = +3x. spaced in a line as shown below. The charges on the spheres are qk = +2x, qL = -6x, 2. Refer to the above information. The methods of charging objects in steps 1, 2, and 3, respectively, are conduction, induction, and friction friction, conduction, and induction 2 Fe induction, conduction, and friction conduction, friction, and induction The direction of the net electric force on sphere L due to spheres K and M is to the right of the page to the left of the page toward the bottom of the page toward the top of the page
