The Correct answer is "2". It is even approved by our physics lecturer.
Let's take an exampl: -5 and 5.
(-5 is not equal to 5, so there are 2 unequal forces)
-5+5=0.
Hence proved.

I think the answer is 2. Definition of equal vectors is that both vectors should have the same magnitude and same direction.
For example, two vectors F and -F have the same magnitude but are in opposite direction. So they are unequal vectors. Hence the answer is 2 (option A).

2 is the most appropriate answer.
Because vectors are equal when their magnitude and direction are equal, Hence if we put 2N force towards east and 2N force towards the west the body will remain in equilibrium.

Answer is three.
I agree because two unequal vectors never gives resultant zero but three unequal vectors give resultant zero.
Ex. We have three vectors N, P and L. N and P goes in same direction and L goes in opposite direction then its resultant is zero.

Two collinear vectors can make zero resultant but they should be of same magnitude and opposite direction in same straight line. When vectors are unequal minimum number required to make zero resultant is three.
