starting with theta in the up position
F=Mv^2 -Mg CosTheta
A small sphere of mass m is connected to the end of a cord of length r and rotates in a vertical circle about a fixed point O. The tension force exerted by the cord on the sphere is denoted by T .
What is the correct equation for the forces in the radial direction when the cord makes an angle θ with the vertical?
