Two equal forces ($P$ each) act at a point inclined to each other at an angle of $120^°$. The magnitude of their resultant is
$P/2$
$P/4$
$P$
$2P$
The resultant of two forces $3P$ and $2P$ is $R$. If the first force is doubled then the resultant is also doubled. The angle between the two forces is ........... $^o$
How many minimum number of coplanar vectors having different magnitudes can be added to give zero resultant
