- Very lost here. Not sure where to even begin. A small sphere with mass mm and charge qq is attached to one end of a string with length LL and tension FTFT. The other end of the string is attached to a wall which has surface-charge density σσ. The angle between the string and the wall is θθ, as shown in the drawing. a.) Please use the interactive area below to draw the Free Body Diagram for the small sphere. (I know the diagram isn't available this way but maybe a drawing?) b.) Enter an expression for the sum of the horizontal components of the forces in the diagram in terms of the variables given in the problem statement and standard physical constants. c.) Enter an expression for the sum of the vertical components of the forces in the diagram in terms of the variables given in the problem statement and standard physical constants. d.) Using the same values, L=L=9 cm, q=q=89 nC, σ=σ=3.4μC/m2μC/m2 and m=m=3.8 g, enter a numeric value for the tension in the string, FTFT, in…Three (3) point charges with q = 7.50 uC are initially held fixed as shown in the figure. The charges are then released, and all three move in response to the electric force between them. Assuming L = 250m, what is the sum of the kinetic energies of the three particles when they are very far apart? Show your work and use significant figures in the final answer. [ Answer: 3.87 J ]Please write all details and properties. I would much appreciate it a lot. Any property or remark, regardless of how insignificant, please include in the answer. Thank you very much.
- Hi, I am having trouble understanding this scenario. Here the charge per unit length on this thin rod shown below is λ. What is the electric field at the point P? Considering the electric field at p is dq = λdx, as a small segment dx of the rod containing the charge . How would I find the net field by integrating over the length of the rod? Any help would be greatly appreciated :)I only need help with question c. Please help. thanksHello, Though I can derive the Taylor series of 1/(1-x), I cannot prove that the x needs to be x << 1. Could you please help me with that? In addtion, how do I derive the formula for the electric field as indicated in (b)? I guess that the x is d/z... but how I can connect this info with the (a) to apply 1/(1-x) Taylor series?
- 2.2Consider an infinitely long cylinder with radius R. The cylinder is an insulator and it is positively charged, the charge per unit of length is A. (Hint: because it is an insulator you should assume that the charge is spread uniformly across its entire volume). By reflecting on the symmetry of the charge distribution of the system, determine what a) the E-field lines look like around the cylinder. Describe the E-field in words and with a simple sketch. In order to give a complete description of the E-field lines make two sketches: i) one with a side view of the cylinder, ii) one with a cross-sectional view of the cylinder. Make sure to also show the direction of the E-field lines. b) (-- . the figure. Your goal for this part is to properly use Gauss' law to calculate the electric field at point P. Follow the 5 steps below. Consider a point P outside the cylinder, at a distance d from its axis, d > R, as shown inPLEASE write the solution on paper.
