itna asan paper main ne ni socha tha. objective was little different but not difficult. it was my first attemp. i do hope to qualify with 170+ if (((resonance ))))occurs between my mind and paper checker...............................ha ha

AoA sister;
You did question related to conservative field i.e Q 4, Paper 1? Especially numerical, variable force?? Can you kindly share method of solving that numerical...... It seems to me a very difficult and ALARMING question!

i dont know my method was right or wrong but i solved it in following way
As displacement is in cordinates and force also in x and y cordinates..........
as on path OBC two paths are ob and bc
we know work formula is W=f.d
f=given
d = x and y = 5 m
first along OB and than along bc and then add these both works and u will find total work along OBC

similarly for other path find work

for the middle path find the displacement of middle path by pythagorus theorm and than find work for it.

if the sum of total work is zero it is conservative other wise non conservative.

note
when u multiply force with displacement, as it is in coordinates and work is dot product so just x multiply with x or y multiply with y. and other coordinate will be zero.

i hope u understand how i attempted this question

Thanks sister. I will further see it in an authentic book. Well can you kindly tell me your method of preparing Physics like books studied, how to use past papers, material research, number of times you revised syllabus etc. I am an engineering student and unluckily have no person to guide me:-(
Even at this forum no one is available for guidance regarding science subjects.....
Thanks again
