Dear Madhu


only presence of charge will not effect the time period


if there is electric field then it will affect the time period.


suppose a electric field E is acting vertically upword direction


then mg-qE is the resultant force in verticle direction


net acceleration g'=g-qE/m


Time period T=2∏√l/g'


                   =2∏√{l/(g-qE/m)}
