Question
Q5 vector field,
In Cartesian coordinates, a vector field takes the form
F = 2rzi+ 2yz j+ (r? + y) k
This question concerns the vector field F defined in Question 5.
(a) State whether F is conservative, and give a one-sentence justification for
your statement.
(b) Calculate the line integral of F along a straight-line path starting at the
origin and ending at the point (a, b, c). This path has the parametric
representation
I = at, y = bt, z= et (0 <t < 1).
(c) Given that the point (a, b, c) could be anywhere, use your answer to
part (b) to find the scalar potential function U(r, Y, z) corresponding
to F, such that F = -VU.
