Question: A +8.75-C point charge is glued down on a horizontal frictionless table. It is tied to a -6.50-C point charge by a light, non conducting

A +8.75-µC point charge is glued down on a horizontal frictionless table. It is tied to a -6.50-µC point charge by a light, non conducting 2.50-cm wire. A uniform electric field of magnitude 1.85 X 108 N/c is directed parallel to the wire, as shown in Fig. 21.39.
(a) Find the tension in the wire.
(b) What would the tension be if both charges were negative?

-2.50 cm- -6.50 µC 8.75 µC

-2.50 cm- -6.50 C 8.75 C
