Six vectors, $\overrightarrow a$ through $\overrightarrow f$ have the magnitudes and directions indicated in the figure. Which of the following statements is true ?
$\overrightarrow {b} +\overrightarrow {c} =\overrightarrow {f} $
$\overrightarrow {d} +\overrightarrow {c} = \overrightarrow {f} $
$\overrightarrow {d} +\overrightarrow {e}=\overrightarrow {f} $
$\overrightarrow {b} +\overrightarrow {e}=\overrightarrow {f} $
The three vectors $\overrightarrow A = 3\hat i - 2\hat j + \hat k,\,\,\overrightarrow B = \hat i - 3\hat j + 5\hat k$ and $\overrightarrow C = 2\hat i + \hat j - 4\hat k$ form
Explain commutative law for vector addition.
Two forces, each of magnitude $F$ have a resultant of the same magnitude $F$. The angle between the two forces is....... $^o$
Two forces of magnitude $3\;N$ and $4\;N $ respectively are acting on a body. Calculate the resultant force if the angle between them is $0^o$
The vector that must be added to the vector $\hat i - 3\hat j + 2\hat k$ and $3\hat i + 6\hat j - 7\hat k$ so that the resultant vector is a unit vector along the $y-$axis is
