In spherical coordinates, find the θ Lagrange equation for a particle moving in the potential field V = V (r, θ, φ). What is the θ component of the acceleration? Hint: The θ Lagrange equation is the θ component of ma = F = −∇V ; for components of ∇V , see Chapter 6, end of Section 6, or Chapter 10, Section 9.
