2. Coulomb's law allows us to find the force between two point charges.Three point charges are held fixed in place as shown.Consider the following comment about this situation:+Qa.+q"There will be zero net electric force on the charge in the middle due tothe other charges. Using Coulomb's law, the force due to the +Q charge is positive, and the forcedue to the -Q charge is negative. The forces cancel."Do you agree with this statement? Explain.-Qb. How does Coulomb's law apply to situations in which there are more than two point charges?

6. Two identical charged particles of mass 70 grams are at the ends of strings that are the same length l = 10 cm attached to the ceiling. The charged particles repel, as shown in the sketch below: The angle between the strings is o = 20°. Use force analysis to develop equations that describe the balance of forces along both the horizontal and the vertical directions. If we let the symbols 'FG' and 'FE' represent gravitational and electric force magnitude, type the symbol in the first answer box that corresponds to the force that balances out the tension along the - direction. In the second answer box type in the symbol for the force that balances out the tension along the , direction. Ft.x L Fr.y =[ Not yet correct, tries 6/18 Submit All Answers Hint: Try to work purely symbolically without substituting any numbers. Draw a free body diagram that shows the forces acting on one of the charged particles. There should be three forces: gravitational, electric, and tension from the string.…
Two charges +2 µC and +8 µC are placed along the z axis, with the first charge at the origin (z =0) and the second charge at z = +1 m. Find the magnitude and direction of the net force on a -2 nC charge when placed at the following locations below. Overall Hint Review Section 5.3 Coulomb's Law. Use Coulomb's Law to calculate force due to each of two charges and add them together for the net force, minding the directions. For part (c), you will need to do the vector sum (more below). a. halfway between the two charges: magnitude of force is direction is Select an answer b. on the axis at x = -0.5 m: magnitude of force is is Select an answer c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +8 µC charge in a direction perpendicular to the line joining the two fixed charges): Hint for (c) This problem is fully 2-dimensional.
