The resultant of two vector will be maximum if they are?
For example we have 2 vectors 𝑎⃗ and 𝑏⃗⃗ and their resultant equals 𝑐⃗. Magnitude of
c equals:
𝑐 = √𝑎2 + 𝑏 2 + 2𝑎𝑏 cos 𝛼
𝛼 – angle between 𝑎⃗ and 𝑏⃗⃗.
c is maximum value if cos 𝛼 = 1 => 𝛼 = 0;
So, when they have the same direction they give maximum resultant.
Answer: The resultant of two vector will be maximum if they have the same
direction.
