Find out potential energy of the two point charge system having charges `q_(1)` and `q_(2)` separated by distance r. |
Answer» Let both the charge be placed at a very large separation initially. Let, `W_(1)=` work done in bringing charge `q_(1)` in absence of `q_(2)=q_(1) (V_(f)-V_(i))=0` `W_(2)=` work done in bringing charge `q_(2)` in presence of `q_(1)=q_(2)(V_(f)-V_(i))=q_(2) (Kq_(1)//r-0)` `:. PE=W_(1)+W_(2)=0+Kq_(1)q_(2)//r=Kq_(1)q_(2)//r` |
