Question

Minimum numbar of vectors of unequal magnitudes which can give zore resultant are

Answer 1

3

Explanation:                              

• We can define a vector by saying that it represents both magnitute and direction we can take some quantities as an example of a vector such as velocity,acceleration,force,momentum etc.
• vectors are usually represented by arrows these arows represent the feature direction of a vector.
• there can be two vectors which can give resultant zero but there must be difference in condition the type of vector must be collinear and the collinear vectors are those which are having opposite direction on same straight line with similar magnitude.  

Answer 2

The minimum number of vectors of unequal magnitudes which can give zero resultant are 3.

• We know that two vectors that are equal and opposite in magnitude give a resultant of 0.
• But, when vectors have unequal magnitudes, a minimum of three are required which satisfy either of the conditions:

1. They form a triangle with rotation in the same sense.
2. They form a straight line with one vector along one direction and the other two summing up to the first and opposite in direction.
