- Problem Description Two small metal spheres A and B have different electric potentials. Sphere A has charge qA = -6x10-6 C and sphere B has charge qB = +2x10-6 C. The radius of sphere A is 0.25 m and the radius of sphere B is 0.50 m. The two spheres are then connected with a wire. Instructions In a neat and organized fashion, write out a solution which includes the following: A sketch of the physical situation with all given physical quantities clearly labeled. If the description above consists of an initial and final state, both of these states should be represented in your sketch. Draw charge diagrams of the spheres before and after they are connected. Charges may be drawn directly on your sketches. Describe in words and mathematically what happens if you connect the spheres with a wire. Calculate the final charge on each sphere after they are connected. What assumptions did you make? Evaluate your answer to determine whether it is reasonable or not.

- This problem is complete the question with proper dimension of rectangular plate. can u assumtion please Please solve max in 20-25 please the subparts A,B,C Im very needed a solution and send thank u A plate plate in a vacuum, has a rectangular area whose sides are 20 cm long. The distance between the two plates is 5 mm. So, A. Make a summary and calculate the value of the capacitance! B. If there is a dielectric material with dielectric constant k = 2 having dimensions of 20 cm x 10 cm x 5 mm is placed between the two plates, then sketch the trainer and calculate the current capacitance value?
