(b) Eight point charges, each of charge -q are placed to form the comers of a cube in space, as shown in the diagram below. Assume these charges are fixed in space. Explain why another identical charge placed at the centre of the cube is not held in stable equilibrium by the electric field. Use both Gauss's law and the electrostatic potential to justify your answer. [5 marks] (c) Write a line integral that relates the electric field due to...
Four equal positive point charges, each of charge 8.1 μC , are at the corners of a square of side 9.2 cm. A). What charge should be placed at the center of the square so that all charges are at equilibrium? Q=__C B). Is this a stable or unstable equilibrium in the plane?
PLEASE HELP so thankful
Charge A feels an electric force of magnitude F created by charge B, which is a distance Raway. If charge B is moved to a distance 3R, what happens to the size of the electric force on charge A? It is reduced to 1/9 its original value It is increased to 3x its original value It stays the same It is reduced to 1/3 the original value Two charges, a +2.0 uC and a -3.0 uC...
Place final answers in the provided answer slots. In order to receive full credit for correct answers all work must be shown. 9. Four point charges are individually brought from infinity and placed at the corners of a square as shown in the figure. Each charge has the identical value +0. The length of the diagonal of the square is 2.0m +la (3 pts). Is the electric force a vector or scalar quantity? (5 pts) Construct a force diagram illustrating...

Q 18.38: A charge Q = a μC is placed on a conducting spherical shell with inner radius Ri 9. 0 cm and outer radius R2 10.0 cm. A point chargeq-b HC is placed at the center of the cavity. The magnitude of the electric field at a point cm f r = c from the center is
Consider the arrangement of charges shown in the figure below. Four charges of equal magnitude Q but varying sign are placed at the corners of a square as indicated. A positive charge q is placed in the center. What is the direction of the net force, if any, on the center charge? Indicate your answer by placing the appropriate label here: + Suppose that the charge q were to be displaced slightly from the center position. On the figure to...
Two point charges are placed on the x axis. Figure 1. The first
charge, q1= 8.00nC, is placed a distance 16.0 m from the origin
along the positive x axis; the second charge, q2= 6.00nC, is placed
a distance 9.00 m from the origin along the negative x axis.
