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

Answer»

Solution :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)`
