Two vectors of magnitude 5 units and 3 units are added such that the angle between the resultant and the vector of magnitude 5units is maximum. Find this angle.
The Attempt at a Solution
Knowing that the resultant vector makes a smaller angle with a vector of larger magnitude, I tried to draw some diagrams but they proved to be of little help.
Further, the max. angle can't be 180 degrees or 0 degree for obvious reasons.
I know PF does not provide complete solutions but I would be thankful for any assistance provided.
