Three forces given by vectors ` 2hati + 2hatj. 2hati -2hatj and - 4hatj` are acting together on a point object at rest. The object moves along the direction.

hati and hatj are unit vectors along x- and y- axis respectively. What is the magnitude and direction of the vectors hati + hatj, and hati- hatj ? What are the components of a vector A= 2 hati + 3hatj along the directions of hati + hatj and hati- hatj ? [You may use graphical method]

hati and hatj are unit vectors along x-axis and y-axis respectively what is the magnitude and direction of the vector hati+hatj and hati-hatj ? What are the magnitudes of components of a vector veca=2hati+3hatj along the directions of hati+hatj and hati-hatj ?
