... Figure 2.27 shows four forces acting on A. In figure 2.28, the resultant of the given forces is determined by the polygon rule. Starting from point O with F1 and arranging the forces in tip-to-tail fashion, we find that the tip of F4 coincides with the starting point O. Thus the resultant R of the g ...

Physics 30 Lesson 16 Electric Potential
... A positively charged particle, with a charge of q, has a certain amount of electric potential at position B (VB) and a different amount of electric potential at position A (VA). The difference in potential is given by: V = VB - VA Thus, when a charged particle is allowed to move from position B to ...

We now show that the force changes sign and becomes repulsive when the charge approaches the z ¼ 0 plane. We can establish the existence of a repulsive regime without any calculation if ...
