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)}
