(Round your answers to the nearest 0.1 µC.) smaller µC. larger µC (b) What if the force were attractive? smaller µC. larger µC
1 Two small identical small spheres with mass m are hung from an insulating threads of length L, as shown in the gure. Each sphere has the same charge q1 = q2 = q. The radius of each Take a small piece ds on ring. Its charge is dq = (Q/2πa)ds and produces a contribution. Then for the total potential.

Click here👆to get an answer to your question ️ Two identical small conducting spheres carry charges of Q1 and Q2 with Q1 >> Q2 . The spheres are d distance apart. The force they exert on each other is F1 . The spheres are made to touch each other and then separated by a distance d. The force they exert on each other now is F2 . Then F1/F2 is : -
• 2. Two metallic spheres of radius 2 cm and 4 cm and both carry equal charges of 30 ?C. If two spheres are connected by conducting wire, then amount of charges will be transferred from one to other is 1 point (1)20 ?C (2)40 ?C (3)10 ?C (4) 30 ?C Other: 3. Force between two identical spheres charged with same charge is F.
• Assuming that the net charge resides at the points of the spheres most distant from each other because of the charge repulsion, we can set the force of repulsion equal to the weight of a sphere. The radius of a one cm 3 sphere is 0.62 cm, so we will treat the force as that between two point charges 2.48 cm apart (i.e., twice the sphere diameter ...
• Solve for q1. q1 = Fer^2 / Kq2. Where. Fe= electrostatic force. r = distance between charges. K = the constant (8.99 x 10^9 N * m^2/C^2) q1 and q2 = point charges. Now just plug in your numbers,...
• 1. Two identical conducting spheres A and B carry equal charge Q. They are separated by a distance much larger than their diameters. A third identical conducting sphere C carries charge 2Q. Sphere C is first touched to A, then to B, and finally removed. As a result, the electrostatic force between A and B, which was originally F, becomes: Solution:
• Initially, electrostatic force between two charges is given by - F1 = k.Q1.Q2/d² When spheres touch each other, charges will be redistributed such that both spheres will have charge Q1/2 (Q2 is negligible). F2 = k.

An infinite line charge produces a field of 9 × 10 4 N/C at a distance of 2 cm. Calculate the linear charge density.

10. Two equal negative point charges repel each other with a force of 18.0 mN. What is the charge on each object if the distance between them is 9.00 cm? How many extra electrons are on each object? 11. Two charged conducting spheres have net charges of +4.0 μC and -8.0 μC and attract each other with a force of 16 mN.
Presentation on theme: "Example: A spherical capacitor consists of a spherical conducting shell of radius b charge -Q concentric with a smaller conducting sphere of Consider two capacitors, each having plate separation d. In each case, a slab of metal of thickness d/3 is inserted between the plates.

English: Electric field around two identical conducting spheres at opposite electric potential. The shape of the field lines is computed exactly, using the method of image charges with an infinite series of charges inside the two spheres. Field lines are always orthogonal to the surface of each sphere.

In a stable equilibrium, if the proton is displaced slightly, it returns to the equilibrium position. Example, Charge Sharing: Fig. 21-10 Two small conducting spheres A and B. (a) To start, sphere A is charged positively. (b) Negative charge is transferred from B to A through a connecting wire. (c) Both spheres are then charged positively.
