could someone explain question 7b to me. on the link you will find the answer to 7b but i do not understand the answer. i do not understand why they write R2<R1 and i don't see how this implies F2=uR2 and i also don't understand how this gives the least value of u necessary for equilibrium http://thephysicsteacher.ie/Exam%20M...hemes/2005.pdf
