Answer» `Q//3`  `q_(1)+q_(2)=0` `v_(A)=(kq_(1))/(R)+(kQ)/(2R)+(kq_(2))/(4R)` `v_(C)=(kq_(1))/(4R)+(kQ)/(4R)+(kq_(2))/(4R)` `v_(A)=v_(C)` `q_(1)=-(Q)/(3)` and `q_(2)=(Q)/(3)` `v_(A)=K[(-Q)/(3R)+(Q)/(2R)+(Q)/(12R)]=(Q)/(12piepsilon_(0)R)]=(Q)/(16piepsilon_(0)R)` `v_(B)=k[(-Q)/(6R)+(Q)/(2R)+(Q)/(12R)]=(5Q)/(48piepsilon_(0)R)` |
