1.	Which of the following statements is / are true? 1.Set of two vectors →a,→b is linearly dependent if and only if either any of →a and →b is zero or they are parallel 2.→a,→b and →c are linearly dependent ⇔→a,→b and →c are coplanar.
Answer» Which of the following statements is / are true? 1.Set of two vectors $\to a, \to b$ is linearly dependent if and only if either any of $\to a and \to b$ is zero or they are parallel 2. $\to a, \to b and \to c$ are linearly dependent $\Leftrightarrow \to a, \to b and \to c$ are coplanar.
