Concepts Of Physics MCQ Edition [Volume 1]PhysicsPhysics and Mathematics
Suppose the resultant of vectors A and B makes an angle with A and an angle with B . It follows that
Options
- A<
- B< if A = B
- C< if A < B
- DB
Correct answer
D. B
Step-by-step solution
Let be the angle between vectors A and B . The resultant vector is given by R = A + B . Using the sine rule in the triangle formed by vector addition: A = B = R (180^ - ) = B A If A > B , then B A This implies Since + = 180^ , we get Thus, the resultant is always inclined closer to the vector with the larger magnitude.
