The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.
For simple pendulum of length L is equal to the radius of the earth 'R', L = R = 6.4 x 106 m, then the time period T = 2π √R/2g. For infinitely long pendulum L > > R near the earth surface, T = 2π × √(R/g)
