Two points charges , each `Q` , are fixed at separation `2d`. A charged particle having charge `q` and mass `m` is placed between them.

(b) If charge `q` is negative and it is displaced slightly perpendicular to the line joining the charges , repeat the part `(a)`.

A charged particle of mass m having charge q remains in equilibrium at height d above a fixed charge Q . Now the charged particle is slightly displaced along the line joining the charges, show that it will executes S.H.M. and find the time period of oscillation.

Two indentical point charges having magnitude q each are placed as shown if fig. If we place a negative cahrge (of magnitude -q and mass m)at the midpoint of charges and displaced along the x-axis, examine whether it will perform simpe harmonic motion. If yes then find the time period of oscillation of the particle.

Two indentical point charges having magnitude q each are placed as shown if fig.
