Question

"Minimum no. of unequal coplanar vectors whose sum can be zero is three". Please explain the statement.​

Answer 1

Since this question lacks specifications about the meaning of the word 'unequal', we have to consider the case of perfectly unequal vectors, that is, unequal both magnitude as well as direction. In that case the minimum number of unequal vectors whose sum can be zero is 3. So, the correct answer is “Option C”.
