A mass is suspended from a spring have 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)/(2 pi^(2))`

Text Solution

Verified by Experts

The correct Answer is:
c
Time period of oscillation of the block
`T=2pi sqrt(m)/(k)rarr (T_(2))/(4pi^(2))=(m)/(k)`
or `(m^(2)k)/(4pi^(2))` n ltbgt weight of the mass w = mg =`(kT^(2)g)/(4pi)^(2)`
