Two otherwise identical conducting spheres carry charges of +4.80 µC and –1.00 µC. They are initially a distance L apart. The distance L is much larger than the radii of the spheres. The spheres were brought together, touched, and then returned to their original separation L. What is the ratio of the magnitude of the force on either sphere after they are touched to that before they were touched?
Two small balls, each of mass 3.0 g, are attached to silk threads 30 cm long, which are in turn tied to the same point on the ceiling, as shown in the figure. When the balls are given the same charge Q, the threads hang at 0 = 3.0° to the vertical. What is the magnitude of Q?
Two identical spheres are attached to silk threads of length L=0.60 m and hung from a common point as shown in the figure. Each sphere has a mass m=7.0 g. One sphere is given a charge q1, and the other is given a different charge q2, this causes the spheres to separate so that when the spheres are in equilibrium, each thread makes an angle = 20 degrees with the vertical. A small wire is then connected to the spheres, allowing charge to be transferred from one sphere to the other until the two spheres have equal charges, the wire is then removed. Each thread now makes an angle = 30 degrees. Determine the original charge (in micro-coulomb) of q1.
Imagine a setup as below, where the Green object is attached to the ceiling with a rotatable rigid rod, and an Orange object is fixed to a wall and d .. m1 Q1 m2 Q2 The Orange object has a charge configuration of Q2 = -10 Coulombs. The Green object's charge configuration Q1 is unknown. The distance between the center of the Orange and Green objects is d=8 millimeters. The mass of the Orange object is m, (the value is irrelevant for this question) and the Green object has a mass of m, = 11 grams. The setup is in equilibrium, that is, the net force on the Green object is zero (hence, it has zero acceleration). If the angle is 0=6 degrees, what is the value of the Green object's charge Q, in Coulombs? IMPORTANT: The actual answer is in the form of 10 18. Write only the number before it. Example: If your answer is 88.888 x 1018 enter only the 88.888 In order to solve this question, you must - Use Sl units (that is, all units must be converted to and evaluated as meters, kilograms, seconds,…
