Solution :
Let 
be the unit vector in the direction parallel to the plane and let 
be the component of F in the direction of 
and 
be the component normal to .
Since, 
Therefore, 
From figure,
We know that the direction of 
is opposite of the direction of , so we have
The unit vector in the direction normal to the plane, 
has components :
Therefore, 
From figure,
∴ 
Therefore,
