An ideal massless spring is compressed by 1 m by a force of 100 N. The same spring is placed at the bottom of a frictionless inclined plane `(theta = 30^(@))`. A 10-kg mass is released from the top of the incline and is brought to rest momentarily after compressing the spring by 2m. Through what distance does the mass slide before coming to rest ?
[Hint : Apply work-energy theorem]

A

`sqrt(20)m//s`

B

`sqrt(30)m//s`

C

`sqrt(10)m//s`

D

`sqrt(40)m//s`
