Compare the components of vector equation `vecF_(1)+vecF_(2)+vecF_(3)=vecF_(4)`.

Text Solution

Verified by Experts

We can resolve all the vectors in x, y and z components with respect to Cartesian coordinate system.
Once we resolve the components we can separately equate the x components on both sides, y components on both sides, and z components on both the sides of the equation, we then get
`F_(1x)+F_(2x)+F_(3x)=F_(4x)`
`F_(1y)+F_(2y)+F_(3y)+F_(4y)`
`F_(1z)+F_(2z)+F_(3z)+F_(4z)`
