A mass is suspended from a spring having spring constant k is displaced veritcally and relased. It oscillates with period T the weight of the mass suspended is (g= gravitatioanal acceleration)A. `(KTg)/(4pi^(2))`B. `(KT^(2)g)/(4pi^(2))`C. `(KTg)/(2pi^(2))`D. `(KT^(2)g)/(2pi^(2))`

Answer» Correct Answer - b
`T=2pisqrt((m)/(k))`
`T^(2)=4pi^(2)(m)/(k)`
`mg=(kT^(2))/(4pi^(2))g`
`W=(KT^(2))/(4pi^(2))`
