(A) The resultant $R$ of two vectors $\vec{A}$ and $\vec{B}$ is given by $R = \sqrt{A^2 + B^2 + 2AB \cos 	heta}$,where $	heta$ is the angle between the vectors.For the resultant $R$ to be maximum,the value of $\cos 	heta$ must be maximum.The maximum value of $\cos 	heta$ is $1$,which occurs when $	heta = 0^o$.Therefore,the angle between the two vectors must be $0^o$ for their resultant to be maximum.

For the resultant of two vectors to be maximum,what must be the angle between them? $(^o)$
