Homework Statement 2 stars rotating around the common centre of mass have masses m and 3m. What is the ratio of the force due to each star at the common centre of mass. Homework Equations None The Attempt at a Solution I tried to find the centre of mass and applied Newtons law of...

thanks pion i have solved it using your way and the answers tally with my results earlier on, thanks alot.

yes it is fixed at 30 degrees. By the way i just solved for another more realistic ans for 672N<p<1920N

AB and BC are 2 strings that are connected at the point where the 960N acts and force P is not a string but rather just a force applied at the angle of 30degrees. But from your equation, it seems that you totally ignored the tension in BC, shouldn't it be also included into the x direction?

ok i got it my ans is p<-1804 or p>1920 is it possible? thanks

i don't quite seem to get you. which 2 forces are you talking about? you mean p and the 960N?

Homework Statement The question is to find the range of values of force p such that the two strings in the picture remain in tension Homework Equations None. The Attempt at a Solution I tried to solve using moments about point C such that i can cancel out the tension in BC but it...
