A block of mass m is released from rest ...

A block of mass m is released from rest at point A. The compression in spring (force constant k) when the speed of block is maximum is found to be `(nmg cos theta)/(4k)`. What should be the value of n?

A

2

B

Text Solution

Verified by Experts

The correct Answer is:
C

Speed of block will be maximum when
`mg cos theta=kximpliesx=(mg cos theta)/(K)`
Where x is compression. So `n=4`
