If $A = 3\hat i + 4\hat j$ and $B = 7\hat i + 24\hat j,$the vector having the same magnitude as $B$ and parallel to $A$ is
$5\hat i + 20\hat j$
$15\hat i + 10\hat j$
$20\hat i + 15\hat j$
$15\hat i + 20\hat j$
Distinguish between Vector quantity and a Scalar quantity.
A physical quantity which has a direction
Explain position and displacement vectors. How the magnitude of vector quantity is represented ?
The expression $\left( {\frac{1}{{\sqrt 2 }}\hat i + \frac{1}{{\sqrt 2 }}\hat j} \right)$ is a
Given vector $\overrightarrow A = 2\hat i + 3\hat j, $ the angle between $\overrightarrow A $and $y-$axis is
