Document Summary
Suppose a 1. 0 g nugget of pure gold has zero net charge. A k+ ion and a cl- ion are directly across from each other on opposite sides of a membrane 9. 0 nm thick. What is the electric force on the k+ ion due to the. Three point charges are fixed in place in a right triangle as shown in the diagram. What is the electric force on the +1. 0. Sketch the electric field lines in the plane of the page due to the charges shown in the diagram. Two tiny objects with equal charges of 7. 00 c are placed at the two lower corners of a square with sides of 0. 300 m, as shown. Find the electric field at the point b midway between the upper left and right corners. Find the electric field at point c, the center of the square. An electron is projected horizontally into the space between two oppositely charged metal plates.
