Lecture - 2 Chapter 10 Vector Algebra
“What you put out is what you get back.”
Topics discussed in this video:
Magnitude of Vectors, Formula to find vector using coordinates of initial and terminal points, Direction ratios, unit vectors, multiplication of vectors by scalar using Geogebra
| NCERT EXERCISE 10.2 |
1. Compute the magnitude of the following vectors:
\vec{a}=\hat{i}+\hat{j}+\hat{k}
\vec{b}=2\hat{i}-7\hat{j}-3\hat{k}
\vec{c}=\frac{1}{\sqrt{3}}\hat{i}+\frac{1}{\sqrt{3}}\hat{j}-\frac{1}{\sqrt{3}}\hat{k}
10. Find a vector in the direction of vector 5\hat{i}-\hat{j}+2\hat{k} which has magnitude 8 units.
