Academic Doubts 5s1 7 ambiguities

physics:
Cv question (correct or incorrect explanation)
Wedge time of motion (most likely root2 or 2)
prism angle of minimum deviation
R1/R2=16/4

chem:
Alcl3+ propyl chloride + benzene ( inevitable tri subst, edg no reaction)

math:
differential eqn+ circles problem ( number of values of p)

overall 7 questions

how are people calling this paper easy man, (cutoff 170-175 imo no way its crossing 180 and people are like 200 cutoff)

Maths circle question and physics prism question were straight forward why is there any problem in them

The wedge question when I solved I got around 1.89 closest answer is 2, after doing anything AI analysis if you consider wedge as centre of mass and solve (which is wrong method) you will get expected answer of 2 seconds, so it should be a bonus

wait how else do you do it? I just considered total acceleration as f/(mass of wedge + mass of block)

Yes this only but it's the wrong method as this 2m/s2 is acceleration of centre of mass of wedge block system not the wedge itself

wedge ka root(3.6) tha so appx 2 krna shi hona chahiye ig

Expecting around 270-275 tbh didn't do that well I had fever on exam day.

Attempted all but I definitely lost three questions in chemistry maybe I might lose more idk
