2005 AP Physics B Form B

  1. May 21, 2005 #1
    I have been working on the 2005 AP Physics B Free-Response Questions from Form B. Question 3 is giving me a lot of difficulty, and I am not sure if i am going in the right direction. The question can be found here:

    http://www.collegeboard.com/prod_downloads/ap/students/physics/ap05_frq_physics_b_form_b.pdf

    For part a, the force on the -Q charge is (2KQ^2)/5a^2, from each of the -2Q charges. To find the net force, do I have break that into X and Y components and add them together as vectors?

    Thanks for your help,
    -joe

    Yes, the net force is in the positive x direction, the y forces cancel.
