Given vector $\overrightarrow A = 2\hat i + 3\hat j, $ the angle between $\overrightarrow A $and $y-$axis is
${\tan ^{ - 1}}3/2$
${\tan ^{ - 1}}2/3$
${\sin ^{ - 1}}2/3$
${\cos ^{ - 1}}2/3$
What is vector ? How it can be represented ?
A vector is added to an equal and opposite vector of similar nature, forms a ........
A plane covers $500 \,m$ in direction $60^o$ with run-way while starting the flight. Find the distance covered by plane in horizontal and vertical direction.
A particle is moving with speed $6\,m/s$ along the direction of $\vec A = 2\hat i + 2\hat j - \hat k,$ then its velocity is
