Question

Two similar conducting balls having charges +q and - q are placed at a separation d from each other in air. The radius of each ball is r and the separation between their centres is d(d >>r). Calculate the capacitance of the two ball system (1) 4 pi epsilon r (2) 2 pi epsilon r (3) 4 pi loge (epsilon r/ d) (4) 4 pi loge (r/d)​
