**1. Two blocks made of different materials connected together by a thin rope, slide down a plane ramp inclined at an angle θ to the horizontal (block B is above block A). The masses of the blocks are mA and mB, and the coefficients of friction are μA and μB. If μA < μB, find the tension in terms of mA, mB, and θ**

**2. The first part of the question is to find the accelearation, a, which I've done and got the correct answer. Finding the tension is the second part of the question, which I've no idea at all how to do. Also, I'm not sure I really understand what tension is.**

**3. I've tried T=Fa-Fb ,but I didn't get the answer.**
