Question

1) Is it possible to add three vectors of equal magnitude but different directions to get
null vector? Illustrate with diagram.​

Answer 1

Answer:

Yes, it is possible to add three vectors of equal magnitudes and get zero. This can happen if the resultant of the two vectors are equal and opposite in direction to the third vector. Thus the vector sum of the three vectors is zero.

Answer 2

Answer:

Yes, it is possible to add three vectors of equal magnitude but in different directions, to result in a null vector.

Explanation:

Suppose we add three vectors in such a way that they form the sides of the triangle. Let the three vectors a, b, and c add a vertex to the base of the tail such that the angle between them is 120° and forms the sides of an equilateral triangle. A null vector is the resultant of joining the tails of the first vector (A) and the last vector (C).
