Question 1 (20 points) Use the spherical coordinates to evaluate: SS SB(² + y² +2²)²dV where B is the ballwith center the origin and radius 5. Question 2 (20 points) Find the work done by the force field F(x, y) = 4xi + (5y+6)j in moving an objectalong an arc of the cycloid r(t) = (t - sin(t))i + (1 - cos(t))j, 0≤t≤ 2T. Question 3 (20 points) Determine whether or not F= 2yi + (2x - 2y)j is conservative. If it is conservative find a function f such that F= Vƒ
