General Physics II Homework 1 Worked Examples Giancoli : 16.13, 16.16, 16.20, 16.22 13. The forces on each charge lie along a line connecting the charges. Let the variable d represent the length of a side of the triangle, and let the variable Q represent the charge at each corner. Since the triangle is equilateral, each angle is 60 o . The direction of is in the y -direction . Also notice that it lies along the bisector of the opposite side of the triangle. Thus the force on the lower left charge is of magnitude , and will point . Finally, the force on the lower right charge is of magnitude , and will point . 16. Take the lower left hand corner of the square to be the origin of coordinates. Each charge will have a horizontal force on it due to one charge, a vertical force on it due to one charge, and a diagonal force on it due to one charge. Find the components of each force, add the components, find the magnitude of the net force, and the direction of the net force. At the conclusion of the problem is a diagram showing the net force on each of the two charges.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
