Question

howresultant of two vectors will be maximum when they are along in the same direction and will be minimum when they are opposite in direction

Answer 1

Answer:

This is b'cuz vectors follow vector law of addition.

Explanation:

i.e.

| Ā+B |= ( A^2+ B^2+ 2ABcosØ) ^1/2

when in same direction Ø1 = 0 & in opposite direction Ø2 = 180 therefore cos ø1 = +1 and cos ø2 = -1 hence making the values maximum and minimum respectively .
