Hey there

your question is unclear but if you are asking about easiest chapters in physics for neet then there are few

1. Unit and dimensions it is the easiest and not much tricky question is framed out of it.

2. Electromagnetic waves is on theoretical side and thus will be easier than others

3. Electricity chapter will be easy as compared to others as many concepts will be from previous classes and thus you can easily understand the chapter.

Good luck
