Homework Statement
We have two balls connected by a string. Let's assume string has no mass. One ball is on the table, spinning in circle at a constant speed, connected by string to a hole with another ball, hanging.
Homework Equations
Finding equation is the problem here.
The Attempt at a Solution
Obviously Force of ball hanging is F=m1*g
But how do I compare that to force of second ball?
I thought about comparing it to centripetal force, or to use torque, however torque unit (Nm) cannot be compared to (N), or at least I don't know about it.
