Question

"Explain the following w.r.t. associating it with vector.
a) The length of a wire bent into a loop
b) A plane area
c) A sphere"

Answer 1

a] No we cannot associate a vector with length of wire bent into a loop. Because the length of loop does not have a definite direction.

b] We can associate a vector with a plane area. Such a vector we call it as Area vector .
Area vector is always represented by a normal drawn outward to the area.

c]The area of sphere does not point in any definite direction. Hence we cannot associate vector with the volume of sphere.

Answer 2

Answer:

we cannot associate a vector with length of wire bent into a loop. Because the length of loop does not have a definite direction.
