A 8.85 ?C point charge is glued down on a horizontal frictionless table on the right. If is tied to a -6.65 ?C point charge by a light nonconducting wire with length 2.5 cm on the left. The charges are placed in a external, uniform electric field with magnitude 1.70 x 10^8 N/C that is directed parallel to the wire to the right toward the positive charge from the negative charge. Find the tension in the wire. What would the tension by if both charges were negative? Go through the math for both questions.
