Which of the two is a better expression for the time period of a simple pendulum?
t-=2∏[itex]\sqrt{(l/g)}[/itex] or t=2∏[itex]\sqrt{(1/T/m)}[/itex] ; l=length of the pendulum
T=time period of the pendulum
m=mass of bob
Note:g is not equal to T/m as there is pseudo centrifugal force such that T + centripetal force=mg
