1.	For the resultant of the two vectors to be maximum, what must be the angle between them
Answer» Answer: The angle should be 0°. Explanation: LET A and B be TWO vectors such that A and b have DIFFERENT magnitude but are in equal direction or parallel to each other then the angle between them is 0°. And we know that Resultants of two vectors is given by :- $\boxed{\sf{R = \sqrt{ {a}^{2} + {b}^{2} + 2ab \:<klux>COS</klux> \alpha } }}$ where $\\alpha$ is angle between two vectors. We know that cos 0° = 1 is maximum on all cos angle. Therefore, The resultants of two vectors is maximum when the angle between them is 0. or, Either they are parallel to each other.

Answer»

Answer:

The angle should be 0°.

Explanation:

LET A and B be TWO vectors such that A and b have DIFFERENT magnitude but are in equal direction or parallel to each other then the angle between them is 0°.

And we know that Resultants of two vectors is given by :-

$\boxed{\sf{R = \sqrt{ {a}^{2} + {b}^{2} + 2ab \:<klux>COS</klux> \alpha } }}$

where $\\alpha$ is angle between two vectors.

We know that cos 0° = 1 is maximum on all cos angle.

Therefore, The resultants of two vectors is maximum when the angle between them is 0.

or,

Either they are parallel to each other.
