A and B are unit vectors with an angle of 120 degrees between them. Determine magnitude of 3A + 2B. ) (TIPS
To find the magnitude of 3A + 2B, we need to add 3A and 2B.
The angle between A and B is given as 120 degrees. The component of 3A in the direction of 2B is given by -3A* cos 30.
So we have 2B -...
