If a simple pendulum has significant amplitude (upto a factor of \( 1 / e \) of original) only in the period between \( t=0 \) s to \( t=\tau s \), then \( \tau \) may be called the average life of the pendulum. When the spherical bob of the pendulum suffers a retardation (due to viscous drag) proportional to its velocity, with ' \( b \) ' as the constant of proportionality, the average life time of the pendulum is (assuming damping is small) in seconds :https://bit.ly/YTAI_PWAP https://www.pw.live
