NCERT Class 12 Maths · Chapter 10 Vector Algebra · Exercise 10.3 Question 1
Find the angle for |a|=√3, |b|=2 and a·b=√6.
💡 Concept Hints
- Write the vector components and identify the required direction or geometric relation.
- Use the magnitude, dot-product, cross-product or section formula that matches the requested quantity.
✅ Step-by-Step Solution
Final Answer: π/4.
- Use cos θ=(a·b)/(|a||b|)=√6/(2√3)=1/√2.
- The vector angle is in [0,π], giving θ=π/4.
