A ball of mass \( m \mathrm{~kg} \) hangs from a spring of spring constant \( k \), The ball oscillates with a period of \( T \) seconds. If the ball is removed, the spring is
P
shortened (w.r.t. length in mean position) by
(1) \( \frac{g T^{2}}{(2 \pi)^{2}} \) metre
(2) \( \frac{3 T^{2} g}{(2 \pi)^{2}} \) metre
(3) \( \frac{\mathrm{Tm}}{\mathrm{k}} \) metre
(4) \( \frac{T k}{m} \) metre
