The vectors ( A + B ) and ( A - B ) are perpendicular to each other. This is possible under the condition
Options
- A| A | = | B |
- BA B = 0
- CA B = 0
- DA B = 1
Correct answer
A. | A | = | B |
Step-by-step solution
Two vectors are perpendicular if their dot product is zero. ( A + B ) ( A - B ) = 0 A A - A B + B A - B B = 0 Since A B = B A , the equation simplifies to: | A |^2 - | B |^2 = 0 | A | = | B | Answer: | A | = | B |
