Previous Problem List Next (1 point) For each of the following vector fields F, decide whether it is conservative or not by computing curl F conservative, type N Type in a potential function f (that is, â½f = F) If it is not A F (z, y) = (-4z-53) i + (-5a + 2y)I f(x,y) = 0 f(x,y) = N f(x,y,z) = D. F (z, y) (-2 sin y) i + (-10y-2x cos y)I f(x,y)0 f (z, y, z) = 1-2/3 x^3-5/3 y^3 + 1/32^3 Note: Your answers should be either expressions of x, y and z (e g. "3xy 2yz"), or the letter "N"
