Choose the correct answer from the options given below :
$(a) \rightarrow(iv),(b) \rightarrow(i),(c) \rightarrow(i i i),(d) \rightarrow(i i)$
$(a) \rightarrow(iv),(b) \rightarrow(iii),(c) \rightarrow(i),(d) \rightarrow(ii)$
$(a) \rightarrow(iii),(b) \rightarrow(ii),(c) \rightarrow(iv),(d) \rightarrow(i)$
$(a) \rightarrow(i),(b) \rightarrow(iv),(c) \rightarrow(ii),(d) \rightarrow(iii)$
The ratio of maximum and minimum magnitudes of the resultant of two vector $\vec a$ and $\vec b$ is $3 : 1$. Now $| \vec a |$ is equal to
The resultant of these forces $\overrightarrow{O P}, \overrightarrow{O Q}, \overrightarrow{O R}, \overrightarrow{O S}$ and $\overrightarrow{{OT}}$ is approximately $\ldots \ldots {N}$.
[Take $\sqrt{3}=1.7, \sqrt{2}=1.4$ Given $\hat{{i}}$ and $\hat{{j}}$ unit vectors along ${x}, {y}$ axis $]$
Two vectors $\vec A$ and $\vec B$ have magnitudes $2$ and $1$ respectively. If the angle between $\vec A$ and $\vec B$ is $60^o$, then which of the following vectors may be equal to $\frac{{\vec A}}{2} - \vec B$
Five equal forces of $10 \,N$ each are applied at one point and all are lying in one plane. If the angles between them are equal, the resultant force will be ........... $\mathrm{N}$
