Two charged particle of equal mass are constrained to move along X and Y direction. The X – Y plane is horizontal and the tracks are smooth. The particles are released from rest when they were at positions shown in the figure. At the instant distance of q becomes 2r from the origin, find the location of charge Q.

Three equal negative charges, -q_(1) each form the vertices of and equilateral triangle . A particle of mass m and a positive charge q_(2) is constrained to move along a line perpendicular to the plane of triangle and through its center, which at a distance r from each of the negative charges as shown in fig. The whole systen is kept in gravity-free space, Find the tome period of vibration of the particle for small displacement from the equilibrium position.
