$\overrightarrow A = 2\hat i + \hat j,\,B = 3\hat j - \hat k$ and $\overrightarrow C = 6\hat i - 2\hat k$.Value of $\overrightarrow A - 2\overrightarrow B + 3\overrightarrow C $ would be
$20\hat i + 5\hat j + 4\hat k$
$20\hat i - 5\hat j - 4\hat k$
$4\hat i + 5\hat j + 20\hat k$
$5\hat i + 4\hat j + 10\hat k$
A particle is simultaneously acted by two forces equal to $4\, N$ and $3 \,N$. The net force on the particle is
For the resultant of the two vectors to be maximum, what must be the angle between them....... $^o$
$\overrightarrow{ A }=4 \hat{ i }+3 \hat{ j }$ and $\overrightarrow{ B }=4 \hat{ i }+2 \hat{ j }$. Find a vector parallel to $\overrightarrow{ A }$ but has magnitude five times that of $\vec{B}$.
Let $\overrightarrow C = \overrightarrow A + \overrightarrow B $ then
