Question

Q25. For the resultant of the two vectors to be maximum, what must be the
angle between them
(a) 0
(b) 60
(c) 90
(d) 180​

Answer 1

Answer: 0 degree (a)

Explanation:

Resultant of two vectors = $\sqrt{a^{2}+b^{2} +2abcos\alpha }$

where a and b are the two vectors and $\alpha$ is the angle between them.

For $\alpha = 0$, resultant will be maximum = $\sqrt{a^{2}+b^{2}+2ab }$ , because cos $0^{0}$ = 1.

So, for 0 degrees, the resultant of two vectors will be maximum.
