if a b c are three non zero vectors such that a b
Question:
If \( a, b, c \) are three non-zero vectors such that \( a + b + c = 0 \) and \( m = a \cdot b + b \cdot c + c \cdot a \), then:
Show Hint

\( m \leq 0 \)
\( m>0 \)
\( m = 0 \)
\( m = 3 \)
Show Solution
Verified By Collegedunia
The Correct Option is
C
Solution and Explanation
Step 1: Use the given relations.
The condition \( a + b + c = 0 \) implies that the vectors are in equilibrium. The dot products give the value of \( m = 0 \).
Step 2: Conclusion.
Thus, \( m = 0 \).
Final Answer:
\[ \boxed{0} \]
