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
$5\hat i + 20\hat j$
$15\hat i + 10\hat j$
$20\hat i + 15\hat j$
$15\hat i + 20\hat j$
How can we represent vector quantity ?
Let $\theta$ be the angle between vectors $\vec{A}$ and $\vec{B}$. Which of the following figures correctly represents the angle $\theta$ ?
The expression $\left( {\frac{1}{{\sqrt 2 }}\hat i + \frac{1}{{\sqrt 2 }}\hat j} \right)$ is a
The value of a unit vector in the direction of vector $A = 5\hat i - 12\hat j,$ is
$0.4\hat i + 0.8\hat j + c\hat k$ represents a unit vector when $c$ is
