`vec(A)` and `vec(B)` are two vectors in a plane and `vec(C )` is a vector perpendicular to this plance their resultant is :

Options

A. Never zero
B. Zero
C. lies between `vec(A)` and `vec(B)`
D. lies between `vec(A)` and `-vec(B)`

Answer

A

Explanation

Resultant of `vec(A)` and `vec(B)` lies in the plane containing `vec(A)` and `vec(B)` since `vec(C)` is perpendicular to plane of `vec(A)` and `vec(B)` . Hence their resultant can never be zero.
