**The problem statement, all variables and given/known data**

A 1.0kg ball is attached to a rigid vertical rod by the means of two massless strongs each 1.0m long. The strings are attached to the rod at points 1.0m apart. The system is rotating about the axis of the rod, both strings being taut and forming an equilateral triangle with the rod. The tension in the supper string is What is the tension in the lower string? What is the net force on the ball? What is the speed of the ball?

**Relevant equations**

The only equation I can think of is F = mv^2 / r

where m = mass, r = radius, v = velocity, F = Centripetal Force

**The attempt at a solution**

I'm not sure how to do the entire question... does finding the tension need an angle? Because the string is not at the horizontal...
