Can someone explain the answer? I don't understand why it's necessary for that the moment when the force exerted on the smaller block is greatest is when it is on the verge of slipping. Could it not already have been slipped off or maybe even 3/4 way slipped off when the force exerted on the smaller block is greatest. Someone please explain thank you

If it was onthe verge of slipping at any other point it would actually slip off at the maximal extension.
