358061 Charges \(4 Q, q\) and \(Q\) are placed along \(x\)-axis at position \(x=0, x=l / 2\) and \(x=l\), respectively. Find the value of \(q\), so that force on charge \(Q\) is zero.

358062 A charge \( + q\) is placed \((a,0,0)\) and another \( + q\) charge is placed at \(( - a,0,0)\).A charged \( - {q_1}\) is placed at the origin. If it is slightly displaced along \(y\)-axis then

358063 A and \(B\) are two identical spherical charged bodies, which repel each other with force \(F\), kept at a finite distance. A third uncharged sphere of the same size is brought in contact with sphere \(B\) and removed. It is then kept at mid-point of \(A\) and \(B\). Find the magnitude of force on \(C\).

358064 Four point \( + ve\) charges of same magnitude (Q)are placed at four corners of a rigid square frame as shown in figure. The plane of the frame is perpendicular to \(Z\)-axis. If a \( - ve\) point charge is placed at a distance \(z\) away from the above frame \((Z < < L)\) then
