Detailed explanation-1: -From the triangle law of vector addition, we can say that we need at least 3 vectors of unequal magnitude to produce zero resultant.
Detailed explanation-2: -Assertion: The minimum number of vectors of unequal magnitude required to produce zero resultant is three. Reason: Three vectors of unequal magnitude which can be represented by the three sides of a triangle taken in order, produce zero resultant.
Detailed explanation-3: -We know that only triangle is closed figure of minimum side, Sides of triangle represent vector, So the minimum number of unequal vectors whose vector sum can be zero is three.
Detailed explanation-4: -Yes, three vectors having unequal magnitude can add up to give a zero vector. This can occur in the case of a triangle whose each vertex is formed from a head and tail of successive vectors.
Detailed explanation-5: -Minimum number is 2, because 2 vectors of equal magnitude in opposite directions give zero resultant.
