Question

Time period of a simple pendulum is given by : (1) T=2π√(g/l)​​ (2) T=2π√(l/g)​​ (3) T=4π√(l/g)​​ (4) T=4π√(g/l)​​

Answer

T = 2π√(l/g)

Reason — Time period of a simple pendulum is given by T = 2π√(l/g)

where

T = time period

l = effective length of pendulum

g = acceleration due to gravity.
