A block of mass m containing a net positive charge q is placed on a smooth horizontal table which terminated in a vertical wall as shown in figure. The distance of the block from the wall is d. A horizontal electric field E towards right is switched on. Assuming elastic collisions (if any) find the time period of the resulting oscillatory motion in second.\[\left( \frac{q}{m}=1C/kg,E=1\frac{N}{C},d=2m \right)?\]
