two conducting spheres with radii r1 and r2 are located very far apart (drawing is not to scale) so that the charge distributions on the spheres are uniform. they are connected by a very long thin conducting wire. what is the ratio of the charges (σ1/σ2)on the surfaces of the spheres?
A. R¹₂/R²₂
B. R1/R2
C. R2/R1
D. √(R1/R2)
