Two vectors A and B lie in a plane.Another Vector C lies outside this Plane.The Resultatnt A+B+C of these three Vectors. (a)can be zero (b)cannot be zero (c)Lies in the plane of A and B (d)Lies in the Plane of A and A+B

```							a vector is nullified if and only if another vector attached to its tail in opp. direction ofsame magnitude n SAME PLANE only.

A and B forms a resultant vector in AB plane and the resultant of A+B+C cant be zero

```							cannot be zero cleary

```							Since the direction is not defined both the A and B vectors are added so it cant be zero this is the practical imagination of vectors
```

```							It cannot be zero because it is mentioned that the three of the vector are not in same plane. Only two vectors are in same plane. So the resultant of three vectors can never be zero.
```

```							As it is given that the vector A and B lies in the a plane,so their resultant must lies in the same plane; and vector C is given be to in another plane so their resultant never be zero except they are not perpendicular planes.

```							A + B + C = (a + c + g)i + (b + d + h)j + mkExplanation:Let the vectors A and B lie in the plane XY (arbitrary XY plane) and the vector is present outside the plane or any where in the space thenvectors A and B have two co ordinates that isA = ai + bjB = ci + djBut vector C has three co ordinates that isC = gi + hj + mkwhere a , b , c, d ,g, ,h ,m are real numbersand i , j , k are unit vectors along X ,Y and Z directions respectively.NOWA + B + C =  ai + bj + ci + dj + gi + hj + mkA + B + C = (a + c + g)i + (b + d + h)j + mkHenceA + B + C = (a + c + g)i + (b + d + h)j + mk
