ill help ya
let the forces be x and 8-x
considering the resultant to make 90 degree angle with x
then 12^2 + x^2 = (8-x)^2
now you can do the rest
hey x value is coming negative which is not possible as magnitude is always positive
is it so?
yeah I solved it
thats why I also posted it here. I solved using your equation also
maybe as angle between the two vectors is greater than 90 degree so, cos theta will be -ve
arey wah ask stormy or trin. both r geniuses
i sux @ vectors rn, im gonna start it too, atb mate
oi dont ping they will see
sry
xd lol
lol im getting 0
one value as 8 another as 0
ig by magnitude, they meant just the value, don't consider the sign
without considering sign if answer satifsies the equations formed then ig tht should be it!
i m getting 13 and -5 which is satisfying
The answer I got is 13, -5 [ lmk if u want the sol for it]
Usually in question when they ask magnitude of something it means that u just ignore the -ve sign/ give mod of the value u get
So mod 13 and mod -5 which is 13 and 5
Well our teacher completely ignored this fact and said that it was a trick ques and you have to arrange vector differently like in the photo
Which I don't think is right
Shouldn’t the resultant point towards the tail of B?
that was my response also but I guess my teacher dosen't want to accept his mistake and is covering it under the blanket of trick question
I was comfirming If I was right here
Oh not big fan of sirs like that, well acc to me it should point towards B def confirm it tho, did u get the 13, -5 ?
yes I got 13 and -5
and I wrote the magnitude as 13 and 5 as magnitude can't be -ve
Yes when they ask magnitude it means it is just the number or as I said mod of the actual value
ok thanks
