A small sphere carrying a charge ?q? is hanging in between two parallel plates by a string of length L. Time period of pendulum is \[{{T}_{0}}\]. When parallel plates are charged, the time period changes to \[T\]. The ratio \[T/{{T}_{0}}\] is equal to [UPSEAT 2003]

\[{{\left( \frac{g+\frac{qE}{m}}{g} \right)}^{1/2}}\]

\[{{\left( \frac{g}{g+\frac{qE}{m}} \right)}^{3/2}}\]
