***circular motion!*** 1. The problem statement, all variables and given/known data http://www.webassign.net/pse/p6-11.gif A 3.60 kg object is attached to a vertical rod by two strings as in Figure P6.11. The object rotates in a horizontal circle at constant speed 7.20 m/s. (a) Find the tension in the upper string. (b) Find the tension in the lower string. 2. Relevant equations T=mg/costheta m(v^2/r)=Tsintheta 3. The attempt at a solution I tried to solve for r and i got 1.32 but when i plugged it into the equation for tension it said it was wrong. i tried to solve for theta and got 41.3 in order to plug into the equation and it was wrong as well. what am i doing wrong??
