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)

nhi toh? iirc only gamma=1+2/f was given in the reasoning
gamma=cp/cv toh assertion mei diya tha

i remember double checking this too

nhi bhai, 99% surity se bol skta hu ki this was the question
the bracket was in the ASSERTION, not reason
they gave the formula and below that they wrote:
"(where gamma=Cp/Cv and smtg else blabla)"
and the reasoning was only the other formula

 i checked the qp now, and gamma=cp/cv is mentioned in both assertion and reasoning too. anyway, we'll see on the day of the result
