Question: Two straight conducting rods, which are=1.0m=1.0mlong, exactly parallel, and separated by=0.55mm,d=0.55mm,are connected by an external voltage source and anE=19-RE=19-resistance, as shown in the figure. TheT=0.50RT=0.50rod

Two straight conducting rods, which are=1.0m=1.0mlong, exactly parallel, and separated by=0.55mm,d=0.55mm,are connected by an external voltage source and anE=19-RE=19-resistance, as shown in the figure. TheT=0.50RT=0.50rod "floats" above theB=2.5-RB=2.5-rod, inequilibrium.

If the mass of each rod is=25g,m=25g,what must be the potentialVof the voltage source?

=V=
