dynamic particle attachment issue

[noman fareed]

I have attached a rigidbody with two ropes at both ends using dynamic particle attachment (compliance = 0) and apply a force on that body just like in the video in the given link

when I released the force the rope doesn't look attached and a little slower than the body just like in the video
kindly answer...
