How was M1 (Math P/42)? (No discussion)

[DaniyalK]

It was a pretty ordinary paper. I think A will be 40-42.

 

[Huzaifa_12345]

It was easy. I don't see the fuss about Q7, it was very standard and easy. Q6 was harder and probably the only tough one in the paper. I'll be surprised if the GT is any less than 40. Knowing me, I probably left a question or something supremely stupid to lose my standard quota of marks.

last question was the mass added or replaced?

Added.

 

[janasalem]

tension in last question ?

 

[farhan141]

tension in last question ?

4.48 and 3.36

What about the mass in qs 6? I was getting it in negative which is not possible..

YOU got 0.8??

 

[qwertypoiu]

Mass in q6 should be 0.3kg.
Mass in q7 last question was 0.134kg Or 0.138kg I forgot....

How did you calculate it?
(1-m)-T=am and T-m=a ?

(1-m)g - T = (1-m)a

T - mg = ma

Grade threshold will be around 37 max..

i am just confused why is the answer of Q7 last part is smaller than the mass 0.2kg
ring is about to go down so mass should b greater than 0.2kg ???

to friends here,
does cie give marks if method is right but values used, of answer to previous question is wrong???
i made a blunder !wrote tension in RJ as tension in AJ and vice versa, will they deduct marks?if yes then how many ?

Provided that you got those values correct (3.36 & 4.48), that mistake will cost you only 1 mark. Chill

Did you get both these answers?

 

[sara kamal]

Did you get both these answers?

yes...but then using the value of RJ as 4.48 i proceeded with next 2 parts....

Ohh i see. I was talking about the first part. You will lose only 1 mark out of 5 for this mistake. But then how were you able to prove the coefficient in the next part using this value?
