Suppose that in Figure P22.8, (left|q_{2} ight|>left|q_{1} ight|>0) but these particles may carry charges of the same

Suppose that in Figure P22.8, \(\left|q_{2}\right|>\left|q_{1}\right|>0\) but these particles may carry charges of the same or opposite type. A third particle carrying charge \(q_{3}\) is to be placed in this system along the axis such that the vector sum of electric forces on the third particle is zero. In which region-I, II, or III-might this be possible if 

(a) q₁ and q₂ have the same sign and 

(b) q₁ and q₂ have opposite signs?

(c) Under what circumstances can the third particle be placed in region I and have the vector sum of electric forces exerted on it be zero?
