I was doing June 2014 Q7 part (a) (ii), find it here: http://www.examsolutions.net/a-level...June/paper.php
As in the mark scheme, I obtained the two equations for T by resolving each particle's forces:
T= 4mg - 4mg/7
T= 3mg/7 + 3mg
Next, I equated these equations and found that m=1.
I substituted m=1 into one of them and got T=33.6. But the mark scheme just used one equation without finding the value of m and expressed T as T=33.6m.
Would I be penalized for finding m and expressing T more simply?
EDIT: I just realized I made a fatal error and did not find the value of m correctly. I don't know how to delete posts so please just ignore this.
