Work done by a radial force field???

Let F be the radial force field F = xI + yJ. Find the work done by this force along the following two curves, both which go from (0, 0) to (8, 64). (Use the Fundamental Theorem for Line Integrals instead of computing the line integral from the definition) A. If C1 is the parabola: x = t, y = t^2, 0 ≤ t ≤ 8,... show more Let F be the radial force field F = xI + yJ.

A. If C1 is the parabola: x = t, y = t^2, 0 ≤ t ≤ 8, then ∫C1 F · dX =

B. If C2 is the straight line segment: x = 8 t^2, y = 64 t^2, 0 ≤ t ≤ 1, then ∫C2 F · dX =
