Given the two charges 2. on the x-axis, as seen in the diagram below 16 c 36 c the 36c charge's position is fixed at x 0 m, and the 16c charge's position is fixed at x 10m. a charge, q -3 c, is placed at x,- 6.0 m, where the net force on it 0 n. a) [26.3) keeping the location of q, as x, what is the electric potential energy of the 3-particle system? b) (26.3] is the electric potential energy at xy a local minimum, a local maximum, or neither? justify the answer conceptually or mathematically c) [26.4] what is the electric potential at x (assuming the third charge is not there)?
