In this Physics video in Hindi for class 11 we explained representing any vector in Rectangular Cartesian Coordinate Unit Vector notation. We also discussed how to find out the magnitude and the direction of any vector represented in rectangular coordinate unit vector notation. The unit vector along x, y and z axes are represented as i, j and k respectively. • A unit vector along any vector is a vector whose direction is the same as the direction of the given vector, but its magnitude is unity. Unit vector along a vector can be achieved by dividing the vector by its magnitude. A unit vector is nothing but a direction. • For example, vector F = 3 i + 4 j + 2 k. So, vector F is the vector sum of three vectors 3 i, 4 j and 2 k. In other words, we say, the 3 unit is the x component of the vector and, similarly, 4 and 2 units are the y and z components respectively. • The magnitude of vector F is √(3² + 4² + 2²) • The angle made by this vector with the x axis is inverse cosine of (3/F). • The angle made by this vector with the y axis is inverse cosine of (4/F). • The angle made by this vector with the z axis is inverse cosine of (2/F). • ★★★★★★★★★★★★★★★★ • Click to visit the homepage of our channel : / @edupoint.physics • Arijit Daripa • EduPoint, • Dam Road, • Chandil, • Dist- Seraikela-Kharsawan, • Jharkhand, • India.
