Answer with Step-by-step explanation:
We are given that
F=<0,-8>=0i-8j=-8j
The component of force is divided into two direction
1.Along the plane
2.Perpendicular to the plane
1.The vector parallel to the plane will be=
By using
Force along the plane will be=
Force along the plane will be =N
By using
Therefore, force along the plane=
2.The vector perpendicular to the plane=
The force perpendicular to the plane=
The force perpendicular to the plane=N
Therefore,
Sum of two component of force=
Sum of two component of force=
Hence,sum of two component of forces=Total force.
