Two small identical conducting spheres are connected by a conducting wire of length a=4.3 m as shown in the figure below. The system is charged by adding charge $$q_1=-0.87$$ mC to the left sphere and charge $$q_2=-0.16$$ mC to the right sphere.
Find the resulting tension T in the connecting wire:
T= N.
(The spheres are much smaller than the wire length and their size can thus be neglected for this calculation. Also, the wire is very thin so that all the charge can be assumed to reside on the spheres.)
