Problem 1. (1 point) Problem 5. (1 point) Evaluate the line integral xz ds, where C is the line segment Let F be the radial force field F = xi + yj. Find the work done by from (0, 1,6) to (7,5,1). this force along the following two curves, both of which go from (0,0) to (6, 36). (Compare your answers!) Answer(s) submitted: A. If Ci is the parabola: x = 1, y = 1, or $ 6, then F. dr = (incorrect) B. If C2 is the straight line segment: x = 63, y = 36-, 0 / $1. then F . dr= Problem 2. (1 point) JO Answer(s) submitted: Evaluate the line integral / 2xy' ds. where C is the right half of the circle x +y = 16. (incorrect) Answer(s) submitted: Problem 6. (1 point) Evaluate the line integral fcF . dr, where F(x,y,z) = -3xi - (incorrect) yj + zk and C is given by the vector function r() = (sint, cost,!), OSIS 3/2. Problem 3. (1 point) Answer(s) submitted: Compute the total mass of a wire bent in a quarter circle with parametric equations: x = 2cost, y = 2sint, 0
