Question

4. Suppose the same particle from Q3 is moving on a circular arc on the unit sphere, with θ = π/3, and beginning at 0 and ending at /4. Compute the line integral F. dr where the spherical form of the infinitesimal displacement vector, dr-dre, + rd0eθ + r sin(θ) dφ èošhould be used. Here, the spherical vector field is in effect.
