NCERT Class 12 Maths · Chapter 10 Vector Algebra · Exercise 10.2 Question 5
Find the scalar and vector components of the displacement from (2,1) to (−5,7).
💡 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: Scalar components −7,6; vector components −7i,6j.
- Subtract terminal minus initial coordinates: (−5−2,7−1)=(−7,6).
- Thus the vector is −7i+6j; its vector components are the two directed axial terms.
