NEET Physics Mathematical Tools Questions Solved


Two vectors A and B lie in a plane. Another vector C lies outside this plane. The resultant A+B+C of these three vectors

(A)  can be zero

(B)  cannot be zero

(C)  lies in the plane of A &B

(D)  lies in the plane of A & A+B

Resultant of Vectors

(B)

Using triangle law,

       

 A+B+R=0

So R has to lie in same plane as A and B otherwise we will not get zero resultant.

So, A+B+C cannot be zero as C is out of plane
