three particles are arranged on coordinate axes as shown above. Particle A has charge qA = –0.20 nC , and is initially on the y–axis at y = 0.030 m. The other two particles each have charge qB = +0.30 nC and are held fixed on the x–axis at x = –0.040 m and x = +0.040 m, respectively.
a. Calculate the magnitude of the net electric force on particle A when it is at y = 0.030 m, and state its direction.
b. Particle A is then released from rest. Qualitatively describe its motion over a long time.
