Referring to Example 29-9 The Picard approaches starbase Faraway Point with a speed of 0.806 c , and the La Forge approaches the starbase with a speed of 0.906 c . Suppose the Picard now launches a probe toward the starbase (a) What velocity must the probe have relative to the Picard if it is to be at rest relative to the La Forge ? (b) What velocity must the probe have relative to the Picard if its velocity relative to the La Forge is to be 0.100 c ? (c) For the situation described in part (b), what is the velocity of the probe relative to the Faraway Point starbase?

Three point-like charges are placed at the corners of a square as shown in the figure, 28.0
cm on each side. Find the minimum amount of work required by an external force to move
the charge q1 to infinity. Let q1=-2.10 μC, q2=+2.40 μС, q3=+3.60 μC.
A point charge of -4.00 nC is at the origin, and a second point charge of 6.00 nC is on the x axis at x= 0.820 mm . Find the magnitude and direction of the electric field at each of the following points on the x axis.
x2 = 19.0 cm
Four point-like charges are placed as shown in the figure, three of them are at the corners
and one at the center of a square, 36.0 cm on each side. What is the electric potential at
the empty corner? Let q1=q3=+26.0 µС, q2=-28.0 μC, and q4=-48.0μc
