## Answer please Q.5. Two charges - q each are fixed separated by distance 2d. A third charge q of mass m placed at the mid-point is displaced slightly by x (x << d) perpendicular to the line joining the two fixed charged as shown in Fig. 1.14. Show that q will perform simple harmonic - q oscillation of time period. $T={\left[\frac{8{\mathrm{\pi }}^{3}{\mathrm{\epsilon }}_{0}{\mathrm{md}}^{3}}{{q}^{2}}\right]}^{1/2}$
