Two blocks of masses m and 2m are held in equilibrium on a frictionless incline as in the figure. In terms of m and 0, find the following. (Use any variable or symbol stated above along with the following as necessary: g.) T m T2 2m (a) the magnitude of the tension T1 in the upper cord T1 = (b) the magnitude of the tension T2 in the lower cord connecting the two blocks T2 =
