# Tension in Circular Motion!

A heavy particle of weight $$W$$, attached to a fixed point by a light in-extensible string describes a circle in a vertical plane. The tension in the string has the values $$mW$$ and $$nW$$ respectively, when the particle is at the highest and the lowest points in the path respectively . If $$n - m = \alpha$$ then find the value of $$\alpha$$ is
