Find the resultant of two vectors vecP ...

Find the resultant of two vectors ` vecP = 3 hati + 2hatj and vecQ = 2hati + 3 hat j`

Text Solution

Verified by Experts

Let ` vecR = vecP + vecQ`
`= ( 3hati + 2hatj) + ( 2hati + 3hatj)`
` vecR = 5 hatj + 5hatj`
This gives the resultant vector.
magnitude of ` |vecR| = sqrt(25 +25) = 5sqrt2`
Orientation of `vecR , theta = tan^(-1) (5/5)`
` = 45^(@)` with x-axis
