Two small spheres with positive charges 3q and q are fixed at the ends of a horizontal insulating rod, which extends from the origin to the point x=d. As can be seen in figure P23.8 , there is a third small sphere with charge that can slide freely on the rod In what position should the third sphere be in to be in balance? Explain if you may be in stable balance

There could be charge on C, but there is no 1. net charge on C. 2. There cannot be charge on C. There could be charge on C and there is net 3. charge on C. C A metal block containing a cavity and car- rying a net charge –Q is located near a pos- itive charge +q_as shown in the figure. In static equilibrium, can there be any charges on the inner surface C of the cavity?
16. Two point charges qA = +10.0 µC and qB = -40.0 µC and a third particle with unknown charge qC are located on the x axis. The particle qA is at the origin, and qB is at x = 12.0 cm. The third particle is to be placed so that each particle is in equilibrium under the action of the electric forces exerted by the other two particles. a) The diagrams below show a positively charged qC in each of the three possible locations with respect to qA and qB. Draw and label vectors (for example, -->F AB) showing the directions of the forces on all three particles, and circle any of the diagrams in which there are opposing forces on all three charges.
