# OCR M1 - Rings, past paper question. watch

1. I'm stuck on this question, I've worked out angles A and B to be 36.9 and 53.1 degrees. But where do I go from here?

All help appreciated.

Do I do Tsin36.9 + Tsin53.1 = 14 ?

so T = 22.9 N ?

I havn't got the mark scheme :|

It's January 2006 M1 OCR.

2 part b) W is the weight of R.. Is it 18.3 N?

What about part 3?

Is a) Vertically beneath A? (P is the 14N force)

b) 0 Newtons?

its just Tcos(A)=Tcos(B)+mg.. if you did that yes
