If a particle moves from point $P (2,3,5)$ to point $Q (3,4,5)$. Its displacement vector be
$\hat i + \hat j + 10\hat k$
$\hat i + \hat j + 5\hat k$
$\hat i + \hat j$
$2\hat i + 4\hat j + 6\hat k$
The magnitude of a given vector with end points $ (4, -4, 0)$ and $(-2, -2, 0)$ must be
A truck travelling due north at $20 \,m/s $ turns west and travels at the same speed. The change in its velocity be
How many minimum number of coplanar vectors having different magnitudes can be added to give zero resultant
There are two force vectors, one of $5\, N$ and other of $12\, N $ at what angle the two vectors be added to get resultant vector of $17\, N, 7\, N $ and $13 \,N$ respectively
$\overrightarrow A = 2\hat i + \hat j,\,B = 3\hat j - \hat k$ and $\overrightarrow C = 6\hat i - 2\hat k$.Value of $\overrightarrow A - 2\overrightarrow B + 3\overrightarrow C $ would be
