{"problem":"We are on the surface of a rotating sphere with angular velocity `\\( \\omega \\)` in an infinite vacuum at an angle `\\(\\pi/2 - \\phi \\)` to the rotational axis. Consider a particle at some point \\\\(P\\\\) (which is very close to us) on the surface of the sphere and moving along the sphere with velocity parallel to the tangent plane to the sphere at \\\\(P\\\\). Assume the sphere is rotating counter-clockwise when viewed along the rotational axis from a point above the hemisphere where `\\( P \\)` is located. The particle is constrained to move along the surface of the sphere, but there are no other forces on it besides constraint forces.\n\nUse plane polar coordinates (r, \\\\theta), with the origin located at some point close to \\\\(P\\\\), to describe the position of the particle. Assume this coordinate system is fixed on the surface of the sphere. Derive a differential equation for \\\\(\\frac{1}{r}\\frac{d}{dt}\\left(r^2 \\dot{\\theta}\\right)\\\\) in terms of \\\\(\\omega\\\\), `\\( \\phi \\)`, and \\\\(\\dot{r}\\\\).\n\nBy convention, `\\( \\theta \\)` is measured in the clockwise direction when viewed from above the surface of the sphere.\n\nThink step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.","subject":"physics"}
