Two charges of equal magnitude q are placed at a distance 2a Another charge q of mass m, is placed midway between the two charges on X-axis. If this charges is displaced from equilibruim state to a distance `x(x lt lt a)`, then the particle :-

Two point charges +q and -q are placed a distance x apart. A third charge is so placed that at the three charges are in equilibrium. Then

Two identical point charges'of magnitude -q are fixed as shown in the figure below. A third charge +q is placed midway between the two charges at the point P. Suppose this charge is displaced a small distance from the point P in the directions indicated by the arrows, in which direction(s) will +q be stable with respect to the displacement?

Two equal charges q are placed at a distance of 2a and a third charge -2q is placed at the midpoint. The potential energy of the system is

Two free point charges +q and +4q are placed apart a distance x . A third charge is so placed that all the three charges are in equilibrium. Then

Two point charges +q and -q are placed a distance x apart. A third charge is so placed that al the three charges are in equilibrium. Then

Two free point charges +q and +4q are placed apart a distance x. A third charge is so placed that all the three charges are in equilibrium. Then
