HW8: Problem 6 Problem List Next Problem Previous Problem has no 2. (1 point) Letr = (s2 + 3 2)1/2 and consider the vector reloF =-(-n + s), where , component and is independent of z 0 and A is a constant | ), and show that it can be written in the form mk, where α = (a) Find curl (-(-n + , for any constant A (b) Using your answer to part (a), find the direction of the curi of the vector fields with each of the following values of A (enter your answer as a unt vector in the direction of the curl) A =-4, direction = A 1: direction- (c) For each values of A in part (b), what (f anything) does your answer to part (b) tell you about the sign of the circulation around a small circle oriented counterclockwise when viewed from above, and centered at (1, 1, 1)? If A =-4 , the circulation is negative r A 1·the circulation is positive (Be sure you can say how your answer in part (c) would change if the question were about a smali circie centered at (0,0,0)) Note: You can earn partial creait on this problem.
