Class 12 Maths · Vector Algebra · Conceptual Answer #95
If a·a=0 and a·b=0 for real Euclidean vectors, what can be concluded about b?
✅ Step-by-Step Solution
Final Answer: b may be any vector.
- a·a=|a|²=0 implies a=0. Then a·b=0 holds for every b and places no restriction on b.
- b may be any vector.
📋 CBSE Stepwise Marking Scheme
- [0.5 marks] a·a=|a|²=0 implies a=0. Then a·b=0 holds for every b and places no restriction on b.
- [0.5 marks] b may be any vector.
