Question

The minimum number of vectors of unequal magnitude required to produce a zero resultant is :

• A. $2$
• B. $3$
• C. $4$
• D. $morethan4$

Answer 1

Answer: (B)

$3$

If you take 1 vector, the resultant can never be zero. If you take 2 vectors, those should be in equal magnitude and opposite in direction for the resultant to be zero. If you take 3 vectors the resultant is zero.

for example, let's take 3 vectors of unequal magnitude to say 3 units, 2 units, and -5 units, the resultant of these vectors is zero. we can take more than 2 vectors of unequal magnitude for the resultant to be zero.. so the minimum no.of vectors of unequal magnitude for the resultant to be zero and maximum is infinity.
