    circumference of each circle is\[C=2\pi r\]where r is the radius of the circle. velocity is\[v=\frac CT\]where T is the time it takes (in seconds) to make one revolution. centripital acceleration is\[a_c=\frac{v^2}r\]and centripital force is\[F=ma_c\]where m is the mass of the object moving put these pieces together to solve your problem
