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, nonconducting  wire. A uniform electric field of magnitude 1.85

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, nonconducting wire. A uniform electric field of magnitude 1.85 times 108N/C is directed parallel to the wire, as shown in the figure. Find the tension in the wire. What would the tension be if both charges were negative?

Explanation / Answer

When the field is applied, a force is added to this which is the difference between the forces from the field on each charge:

F1 = E*q1; F2 = - E*q2 the difference F = E*(q1 + q2).

The net force is the wire tension, is F + Fc = E*(q1 + q2) - K*q1*q2/L
