A spring of spring constant `200 N//m` has a block of mass `1 kg` hanging at its one end and form the other and the spring is attached to a ceiling of an elevator. The elevator rises upwards with an acceleration of `g//3`.
When acceleration is suddenly ceased , then what should be the angular frequency and elongation during the time when the elevator is accelerating?

A

`14.14 rad s^(-1), 0.07 m`

B
