Answer 1

I can't understand if they mean vectorially or not, as A could mean\[|\mathbf{T_L+T_R}|=|\mathbf{W}|\]

Answer 2

Well,
1 Bold letters are vectors
2 The horizontal projections of T_R and T_:L must balance to 0 - nothing elese will balance them.
Now - which of those two has a larger cos(angle) with the horizontal ?
That tension must be smaller because it balances a more-reduces "opponent".
Think of it @henpen - and light will reveal itself upon you

Answer 3

My final guidabce here - which cosine is larger - that T must be smaller. More than that will spoyl you

Answer 4

Thanks- I understand. Is my intuition correct? And as b_x=a_x, the y components must be f(y). The problem I was having is that the tension is parallel to the string. That was stupid of me!

Answer 5

I mean, I even KNEW the answer (physically), but my erroneous mathematics misguided me.

Answer 6

focus on the guide above

Answer 7

I understand your guide.
