Question

A block of mass m hangs from a vertical spring of spring constant k. If it is displaced from its equilibrium position, find the time period of oscillations.
A. `(sqrt(2pi))/(7) s`
B. `(2pi)/(7) s`
C. `(pi)/(7) s`
D. `(pisqrt(3))/(7) s`

Answer 1

Correct Answer - C
`T=2pisqrt((m)/(K))=2pisqrt((mx)/(mg))=2pisqrt((x)/(g))`
`=2pisqrt((0.05)/(9.8))`
`=(2pi)/(14)=(pi)/(7)s`
