you can use the EDUCATION CATEGORY to find more physics, chemistry and other questions with answer…good luck to us all, do well to keep coming back because that’s the motive behind the name of this site ANSMYQUES (ANSWER MY QUESTION). Or equally you can use the search box above or below TYPE PHYSICS and it will bring out all physics questions on this plattform, this idea can be use for other subjects too.
