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 `bar(R ) = bar(P) + bar(Q)`
`= (3 hati+2hatj)+(2hati+3hatj)`
`bar( R) = 5 hati+ 5 hatj`
This gives the resultant vector.
Magnitude of `|barR|= sqrt(25+25)= 5 sqrt(2) `
Orientation of `bar( R) , theta = tan^(-1) ((5)/(5))`
= `45^(@)` with x- axis
