  12.31: Three particles with chargesQ, -e ugnhy 2htnyad4 ety-1y;zli)p/9* Q and $Q_2$ are initially at rest very (infinitely) far apart from one another. The particles are moved to the locations shown in the figure where they are fixed in place. The particles on the left and right have charge Q and are separated by a distance R. The particle with charge $Q_2$ is located at the midpoint directly between the other charged particles. The total work required to configure this three-particle arrangement is 0. Ignore any self-energies for the particles. What is the value of the charge $Q_2$ ?

  10.37: A positively charged particle is moved in a straight line ttr lm5nsh/k -5o the right from position x = −4.0 m to position x = −2.0 m by an external agent. The elec5l /5 krtnsm-htric potential at these positions in space are V(x = −4m) = −4.0 Volts and V(x = −2m) = −2.0 Volts. Which statement is true about the work done by the external agent moving the charge between these positions and the electric field component parallel to the direction of motion that the moving charged particle experiences? Assume the particle is moved at constant speed.
