Question

Two vectors A and B lie in a plane, another vector C lies
outside this plane, then the resultant of these three vectors
i.e., A + B + C
(a) can be zero
(b) cannot be zero
(c) lies in the plane containing A + B
(d) lies in the plane containing A – B

Answer 1

Answer:

correct option is b

Explanation:

• third vector is outside the plane of the remaining two,so this extra component can't be cancelled by any others during addition or substraction and hence total sum will never be zero..
