Looking at the version that was closed, you have two questions that you're asking:
- What is the intuition for angular momentum of a point mass relative to a inertial point?
- I am confused that at the same time the static friction helps in pure rolling by operating in direction opposite to wheels motion as well as it provides the car the required centripetal acceleration by operating towards the centre. How is it possible?
These are two separate questions. The first isn't clear what "intuition" you seek and what it is you understand. The best we can tell you is what a textbook might say, so you need to clarify what it is that you don't understand and would like further details on.
The second is probably a duplicate of other questions asked in this site (haven't looked to be sure, but it looks like queries I've seen before). It's also not clear how this question relates to the previous one.
You've already removed the second part, so no need to further worry about that. In order to get the question reopened, you need to explain what it is you do understand about angular momentum & how you don't see the connection to the relative inertial point.
Note also that stating "Answer as fast as possible!" is generally not well received, and often results in downvotes. We all here volunteer our time to answering questions, your want of a rapid response seems to not care and/or respect the volunteer nature of this service.
If this is the case the questions are closed on this website then how can we leave this website completely?
Well, the most basic option is to just not come back to this site. If you also want to delete your account (an irreversible process), follow these instructions.
