the problem is that our sir used this concept of angular momentum conservation to solve 2 of the questions of hc verma, i.e, Q81,82.i did question my sir regarding this, but he said that the method was right and he showed that the hc verma solutions also use the same method. could u plz look into these questions and tell me how would u solve them? regarding the 2nd question, the answer is that there does occur a change.the days grow longer. as per the book i am refering.but i didnt understand the reason for this.
