(a)[5%]Is the force field F(x,y,z) = -yi +xj +2k conservative? Why? [Hint]
Consider the work done on moving a point particle along the unit circle
centered at the origin in the xy plane. (b)[5%]For a conserved force field
→ →
F(x,y,z) with potential energy U(x,y,z), show that F is perpendicular to the
equipotential surface U(x,y,z) = constant.
a小題和b小題...麻煩了..
