A frame {B} is located initially coincident with a frame {A}. We rotate {B} about ZB by 9 degrees, and then we rotate the resulting frame about XB by 0 degrees. Give the rotation matrix that will change the descriptions of vectors from Bp to Ap.

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
