If the angle between two vectors $A$ and $B$ is $120^{\circ}$, its resultant $C$ will be
$C=|A-B|$
$C < |A-B|$
$C > |A-B|$
$C=|A+B|$
(c)
Resultant of two vectors lies between $A + B$ and $| A + B |$.
Given $A =\hat{ i }+\hat{ j }+\hat{ k }$ and $B =-\hat{ i }-\hat{ j }-\hat{ k }$, then $( A – B )$ will make angle with $A$
If $\vec{A}+\vec{B}+\vec{C}=0$ then $\vec{A} \times \vec{B}$ is …………
A boat is sent across a river with a velocity of $8\, km/hr$. If the resultant velocity of boat is $10 \,km/hr$, then velocity of the river is ……..$km/hr$
