Two spheres of radii R1 and R2 have equal charge are joint together with a copper wire. If the potential on each sphere after they are separated to each other is V, then initial charge on any sphere was (k = 1/(4piin_(0)))-
A. (V)/(k)(R_(1) - R_(2))
B. (V)/(2k)(R_(1) + R_(2))
C. (V)/(3k)(R_(1) + R_(2))
D. (V)/(k) ((R_(1)R_(2)))/((R_(1) + R_(2)))
