Hi Cathy


On joining the two spheres their potential will become equal


Let the charge remaining on charged sphere be q then by charge conservation, charge on uncharged sphere will be (Q - q).


Their potential will be equal so,


Kq/R = K(Q-q)/2R


=>  q = Q/3


So charge transferred from initially charged sphere to initially uncharged sphere is Q - Q/3 = 2Q/3
