5. Brain Buster: Two conducting spheres with charges Q = 40.0C and Q = 30.0C and respective radii r = 0.10m, r2=0.050m are conducted together with a thin, light conducting wire with a switch in the middle as shown below. The spheres are positioned 2.0m apart (measured from center to center as shown). Q R R2 2m Q2 a. Determine the tension in the wire immediately after the switch is first closed. b. Determine the tension in the wire after the switch has been closed for a LONG time. (hint: overall or total charge of the system must be conserved. After a long time equilibrium will be reached when current stops flowing)
