Exact solutions for gravitational problems involving morethan two bodies are notoriously difficult. One solvableproblem involves a configuration of three equal-massobjects spaced in an equilateral triangle. Forces due totheir mutual gravitation cause the configuration to rotate.Suppose three identical stars, each of mass M, form atriangle of side L. Find an expression for the periods oftheir orbital motion.*I am a complete noob at Physics. Explain all please,even the minor concepts involved.

2. Integrate the equations of motion for a spherical pendulum, i.e., a particle of mass m moving on the surface of a sphere of radius / in a gravitational field, with Lagrangian L = ml² -(0² + psin² 0) + mglcos 0. 2 Hint: Merely set up the integrals, do not evaluate them. You should obtain two integrals w.r.t. de: one determining t and another determining p. Express the first integral in terms of E,Ueff, m, and l. Express the second integral in terms of E,U eff, m, l, and M₂.
