Answer 1

(A) No, it doesn't have uniform direction so, we can't associate q vector with length of a wire bent into a loop.

(B) Yes !! Area is a vector quantity , direction of area vector normally outward .

(C) NO , we can't associate a vector with the volume of the sphere . it is scalar quantity.
