hi mr, reddy
so you are doing solutions chapter of class 12. but did you know the base of this chapter is in syllabus of class 11. yes. so for this you should first do class 11 chapter 7 equillibrium very well and then go with this chapter,
Thenn read notes of chapter “solutions” from this site. read more and more theory because it is helpful in numericals,
try this it will surely work
thanks and approve my answer
note:this method will consume your more days but it gives more benefit also........
thanks again
