Chapter 15, Problem 35(choose chapter or problem)
Use the result in Exercise 34(b).
In each part, find the work done by the three-dimensional inverse-square field
\(F(r)=\frac{1}{\|r\|^{3}} r\)
on a particle that moves along the curve \(C\) .
(a) \(C\) is the line segment from \(P(1,\ 1,\ 2)\) to \(Q(3,\ 2,\ 1)\) .
(b) \(C\) is the curve
\(r(t)=\left(2t^2+1\right)i+\left(t^3+1\right)j+(2-\sqrt{t})k\)
where \(0 \leq t \leq 1\) .
(c) \(C\) is the circle in the \(xy\)-plane of radius 1 centered at \((2,\ 0,\ 0)\) traversed counterclockwise.
