Question

The two vectors A and B are drawn from a common point and C = A + B. The angle between A and B is:

• A. 90^ if C² = A² + B²
• B. greater than 90^ if C² < A² + B²
• C. greater than 90^ if C² > A² + B²
• D. less than 90^ if C² > A² + B² Correct options are —
  (a) 1, 2 (b) 1, 2, 3, 4 (c) 2, 3, 4 (d) 1, 2, 4

Hint:

Remember the vector addition formula to relate magnitudes and angles.
