Choose the correct answer from the options given below :
$(a) \rightarrow(iv),(b) \rightarrow(i),(c) \rightarrow(i i i),(d) \rightarrow(i i)$
$(a) \rightarrow(iv),(b) \rightarrow(iii),(c) \rightarrow(i),(d) \rightarrow(ii)$
$(a) \rightarrow(iii),(b) \rightarrow(ii),(c) \rightarrow(iv),(d) \rightarrow(i)$
$(a) \rightarrow(i),(b) \rightarrow(iv),(c) \rightarrow(ii),(d) \rightarrow(iii)$
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
Find the resultant of three vectors $\overrightarrow {OA} ,\,\overrightarrow {OB} $ and $\overrightarrow {OC} $ shown in the following figure. Radius of the circle is $R$.
Establish the following vector inequalities geometrically or otherwise:
$(a)$ $\quad| a + b | \leq| a |+| b |$
$(b)$ $\quad| a + b | \geq| a |-| b |$
$(c)$ $\quad| a - b | \leq| a |+| b |$
$(d)$ $\quad| a - b | \geq| a |-| b |$
When does the equality sign above apply?
Two forces $3\,N$ and $2\, N$ are at an angle $\theta$ such that the resultant is $R$. The first force is now increased to $ 6\,N$ and the resultant become $2R$. The value of is ....... $^o$
