Question

two vectors vector A and vector B lie in a plane.another vector c lies outside this plane.the resultant of vectorsA+B+C is
A)can be zero
B) cannot be zero
C)lies in the plane of vector A and vector B
D)lies in the plane vector A and vector A+B

Answer 1

Answer:

B) cannot be zero

Explanation:

The resultant for three or more vectors lying in different planes can never be zero, as resultant for first two vectors (A and B) should be in the same plane as them but with the third vector (C) the overall resultant would never be zero.

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