Q.19 Consider the vector ficld F = r®yi-xj). where pER, f=xi+ yj and r = |P1. If the absolute value of the line integralF df along the closed curve C:x+ y =a (oriented counter clockwise) is 2, then f is (A)-2 (B)-1 (C) (D) 2 9.45 Let F = vFf + (x+y*)} bea voctor field for all (x.y) with x 20 and f xf+ yi. Then the value of the ine integral S. F-df from (0,0) to (1, 1) along the path C: x t, y =t", 0stslis,
